CF65/75/85 Series 0E621376 Fault finding
1. FAULT FINDING
The following test equipment and tools can be used to trace faults.
1. The best instrument for this is a digital multimeter. This instrument can be used to measure voltages, currents and resistances avoiding reading errors, and it can be used to trace virtually any faults.
2. Many, but not all, faults are easily traced by means of warning lamps. Failures caused by poor earthing cannot normally be detected by a warning lamp or buzzer.
The most frequently occurring faults are: a. short circuit b. open circuits c. earthing problems (poor earthing due to
corrosion).

1.1 SHORT CIRCUITS
A short circuit is caused by a positive wire shorting to earth somewhere. In most cases this willcauseafusetoblow. To remedy this failure, use a test lamp of approximately 70W. First check the diagram to see which consumers are connected to the fuse in question, and then switch them all off. Remove the fuse and connect the test lamp in its place. Now switch each of the consumers on and off one by one. If the lamp comes on very brightly when a consumer is switched on, the fault is almost certainly in the wiring of that consumer. Now check the diagram to see via which connectors the consumer is connected. Now disconnect the first wiring connection (as seen from the fuse). If the lamp is still bright, the fault is between the fuse and this wiring connection.
If, however, the lamp goes out, the fault is somewhere further on in the wiring. Now reconnect the connectors and disconnect the next wiring connection. If the lamp is still bright, the failure is between these two wiring connections. However, if the lamp goes out again, the fault-finding procedure must be continued. The faulty wiring section can be found in this way.

1.2 OPEN CIRCUIT
Suppose a consumer is not functioning. The fault may be in the consumer itself, or there may be an open circuit in the wiring. First switch on the consumer. Then check the consumer for voltage using a test lamp. If no voltage is found, first check whether the fuse is still intact. If there is voltage at the fuse, check the wiring from the fuse to the consumer. This means every wiring connection must be checked. Stop at the first wiring connection that has no voltage. The open circuit will be between this connection and the previous one. However, if there was a voltage at the consumer, there may still be an open circuit in the negative (earth) wiring. Check this using a test lamp. Ensure that the relevant circuit is switched on. Connect one end of the test lamp to earth and the other end to the earth connection of the component to be checked. If the test lamp lights up, the earth connection of the component is interrupted. If the test lamp does not light up, the earth connection will in many cases be in good condition. If both the positive and negative connections are in good order, the consumer in question must be replaced.

1.3 EARTHING PROBLEMS
Earthing problems are mainly caused by corrosion between the contact surfaces of electrical connections. A poor earth connection of the main earth circuit (2) between cab and chassis may result in a current through the steering shaft (1).
1
To check this main earth connection, two complementary tests must be carried out.
- A current measurement using a current probe.
- A voltage loss measurement using a multimeter.
A current probe, which is a special tool (DAF no.
1453183), must be used for a current
measurement; this measures the current through the steering shaft (1).
The current measurements have to be carried out while the cab is in the driving position.

INSPECTION 1, MEASURING THE SYSTEM CURRENT
1. Open the grille.
2. Switch on vehicle ignition and as many consumers as possible, e.g.:
- dipped beam
- heater fan in position 4
- spotlights, etc.
3. Use the current probe to check whether the power consumption through the battery cable at the battery is between 20 A and 40 A. Switch on extra consumers if this is not the case until the power consumption is between 20 A and 40 A.
4. Then measure the system current through the steering shaft (1) using the probe. Make sure that the current probe is placed in the right position (direction of current) and its jaws are closed around the steering shaft.
5. Depending on the measured current value, the following actions need to be carried out:

To find out whether a specific earthing point has a good earth connection, measure the voltage loss between the negative battery terminal and this earthing point.
The figure shown is an example; the actual course of the earth connection may differ somewhat depending on vehicle type and production date. The consumers that were switched when the current was measured should now be switched on as well, i.e. the power consumption should be between 20 A and 40 A. If the earth connection is good, the voltage loss should be less than 0.5 V.

2.2 SERVICE LIFE
The service life of a battery is significantly shortened if it used “cyclically”. This means that the batteries are used a lot without being charged. For example when using a tail lift, cab heater, microwave oven or cooler box. This is why batteries in commercial vehicles and vehicles used for international transport often fail prematurely (within 1.5 years).
The battery must be charged whenever the voltage measured across the battery falls below
12.5V. If the battery is not charged, the “sulphating process” will begin. This is a chemical reaction in the battery that produces lead sulphate. Lead sulphate adheres to the battery plates and can cause short-circuiting between the plates, reducing the capacity of the battery. However, most lead sulphate breaks down when the battery is recharged. If a battery is used (discharged) while it is not being charged by the alternator, short-circuiting between the battery plates will occur sooner. This reduces the capacity and consequently the service life of the battery.

1.3 SIGNAL MEASUREMENTS
Sine--wave signal (AC voltage)
This signal changes polarity regularly in relation to the “0” line.
Frequency The frequency is shown in Hertz (Hz). The number of complete sines per second is the frequency of the signal (3 Hz in the diagram).
Voltage If the number of sines per second increases, not just the frequency increases but also the voltage.
Measuring a sine wave signal
The sine wave signal can be measured in the following ways using a multimeter:
- Multimeter in the frequency position (Hz). This measures the number of complete sines per second.
- Multimeter in the AC voltage position. This measures the average value of the supplied voltage.
Sine wave signals in the vehicle
- Wheel speed sensor output signal.
- Engine speed sensor output signal.

Square wave signals are signals with only two voltage levels, both of which have the same duration in principle (t1 is equal to t2).
If there is a difference between the duration for the two levels (t1 is not equal to t2), the signal is also called a ”pulse train“.

- engine speed sensor
- camshaft sensor
Recording engine speed
The engine speed is recorded via the crankshaft position sensor. The crankshaft position sensor output signal is a sine wave signal with a frequency corresponding to the number of holes in the pulse disc and the crankshaft rotation frequency. The signal is converted in the electronic unit into a message that is sent via the CAN network. The VIC sends this message to the DIP, which then activates the rev counter.
Engine speed sensor operating principles
The inductive sensor consists of a permanent magnet (1), a core (2) and a coil (3). When the inductive sensor is situated between two teeth, the lines of force of the magnetic field will run directly from the north pole to the south pole via the housing.
The moment a tooth approaches the inductive sensor, the lines of force of the magnetic field will run from the north pole to the south pole via the housing, the teeth of the toothed wheel and the core. As more lines of force are now running through the core, a more powerful magnetic field is obtained. As a result of this change in the magnetic field, an AC voltage is generated in the coil.

2.2 VEHICLE SPEED SENSOR
The vehicle speed sensor has two connections for output signals. The “real-time” speed signal, generated by a Hall IC, is sent via the first connection, A data signal (bi-directional signal) is sent via the other connection, data being exchanged between the MTCO and the speed sensor. The MTCO requests data from the sensor. The sensor sends the coded data to the MTCO in sequence, and the MTCO checks the accuracy of this data. The coded signal consists of the following data:
- Serial number of the sensor
- “Master key” (the same as that of the MTCO)
- Coded speed signal
The MTCO compares the coded speed signal to the “real-time” speed signal. The MTCO sends commands and data to the sensor at 10 second intervals.

Speed data for the CAN-system is sent via MTCO-outputs A6 and A7.
Speed data for the UPEC-system and ECAS-system is sent for UPEC via output B7 and for ECAS via output B6; these are duty-cycle signals.
Duty cycle speed signal
The speed signal sent via the vehicle speed sensor to the MTCO is processed by the MTCO and sent as a message via the CAN network. The speed signal is also converted into a duty cycle signal. This signal is used by electronic units that do not receive/read the vehicle speed signal message via the CAN network. This diagram shows the linear characteristic of the duty cycle (%) in relation to the vehicle speed (V). This graph applies to all vehicle models.

2.3 TEMPERATURE SENSORS
The vehicle has a number of temperature sensors, such as:
- coolant temperature sensor
- inlet air temperature sensor
- fuel temperature sensor
- ambient air temperature sensor
These sensors are temperature-sensitive resistors. Large changes in the resistance of these sensors are perceptible when the temperature rises or drops.
There are two types of temperature sensor:
- NTC resistor (Negative Temperature Coefficient).
- PTC resistor (Positive Temperature Coefficient).
NTC resistor
In an NTC resistor, the resistance value reduces when the temperature rises.
Application:
- measuring coolant temperature.
PTC resistor
In a PTC resistor, the resistance value increases when the temperature rises.
In contrast to the NTC resistor, there will be a large change in resistance within a small temperature range in the PTC resistor.
Application:
- measuring air temperature when cab heater is on

2.4 FLUID LEVEL SENSORS
The vehicle has a number of fluid level sensors, such as:
- cooling system fluid level sensor
- engine oil level sensor
Coolant level sensor
The coolant level sensor consists of two microswitches (reed switches), connected in parallel with two resistors. These microswitches are influenced by a magnetic field positioned outside the sensor. If the coolant level drops, the microswitches will be closed by a float fitted with a fixed magnet.
The “alarm switch” detects that the coolant level is too low and short circuits the parallel switched resistor. The “daily inspection” switch detects that the coolant needs to be topped up and short circuits the parallel switched resistor. The VIC uses the resistance value to detect the status of the microswitches. As a result the instrument display is activated by the VIC.
Note:
The VIC will only send a message to the instruments display during the startup phase if the “daily inspection” switch is closed during the startup phase.
Engine oil level sensor
The operation of the engine oil level sensor is based on a resistance measurement. When the contact is switched on, a current is sent through the sensor from the VIC control unit for a specific period of time. Applying this current briefly in this way ensures that the sensor is properly warmed up. When the level is being measured the resistance value is influenced by the quantity of oil in the sump.

CF65/75/85 series 0E621376 Description of components
Inspection
The engine oil level sensor can be checked with a multimeter set to the resistance range. The resistance value is between 20.5 and 23.5 Ohms, measured at 20_C. The maximum current strength of 200mA may not be exceeded when the resistance value is measured.
2.5 PRESSURE SENSORS
The vehicle has a number of pressure sensors, such as:
- Pressure sensor to record bellows pressure for ECAS.
- Pressure sensor on the air supply unit.
There is a diaphragm made of semi-conducting material (silicon) in the pressure sensor. When pressure is applied to the diaphragm, it will be deflected. Deflection of the diaphragm leads to a change in the resistance of the semi-conducting material.
The diaphragm is part of a what is known as a bridge circuit. Deflection of the diaphragm unbalances the bridge circuit, which changes the output signal. The output voltage is in direct proportion to the pressure applied (deflection of the diaphragm).
Inspection
The output voltage can be checked using a multimeter set to the DC voltage range.

Pressure sensor for monitoring boost pressure.
A piëzo pressure sensor is used to check the boost pressure. This sensor consists of an electronic circuit and a pressure recording element. The pressure recording element records changes in pressure; these changes in pressure are converted into an electrical voltage. The electronic circuit amplifies this voltage to create a usable output signal.
Inspection
The output voltage can be checked using a multimeter set to the DC voltage range.
2.6 ALTERNATOR
The compact alternator is a lightweight alternator with two internal cooling fans. The electronic controller also controls pre-excitation of the alternator. The function of the exciter diodes has also been taken over by the controller. The alternator generates high currents in the lower speed range.

CF65/75/85 series 0E621376 Description of components
Connection 15
When the ignition has been turned on (contact made), power is supplied to the alternator via connection 15 (1010). The controller uses this power to activate pre-excitation (self-energising). If there is an open circuit in this connection, the alternator will not produce any power until it reaches a speed of about 5000 rpm. This corresponds to an engine speed of around 1500 rpm. The alternator will energise itself when it reaches this speed.
Sens connection
The sens connection can be used to compensate for voltage losses in B+. There are voltage differences between the alternator and the battery. Voltage regulation can be improved if these voltage variations can be controlled. The sens connection is connected to terminal 30 on the starter motor.
2
L connection
The L connection is connected to the VIC electronic unit. This connection is used to activate a fault message in the master display via the VIC, if necessary.
L voltage high: no fault L voltage low: fault
The following faults can be detected via the “L” connection:
- Voltage too low (< 16V)
- Open circuit in connection 15 (1010)
- Open circuit in “S” connection
- Open circuit in “L” connection
These faults are indicated by the yellow “Alternator fault” warning.
Too high a voltage (red warning) can be recognised by too high a voltage (>31 V) on the VIC electronic unit.

2.7 PROXIMITY SENSORS
The vehicle has a number of proximity sensors, such as:
- sensor under the clutch pedal for engine
management
- cab lock sensor
- mechanical rear axle lifting-gear
W 5 01 014
Inductive proximity sensor
An alternating electromagnetic field is generated by a pulsating current in a coil (oscillation). If a metal object is introduced into the electromagnetic field, eddy currents will occur in that metal object. These eddy currents will “damp” the magnetic field in the coil, so that the current in the coil changes. This change results in an output voltage.
Inspection
Placing a metal object in front of the sensor (inductive sensor) makes it possible to check the output voltage using a multimeter set to the direct voltage range.

1. GENERAL
The increasing application of electronics in vehicles means a much broader range of connectors, contacts and wiring is being used. Be sure to pay special attention to this during repairs, so as to avoid unnecessary faults.
1.1 CONNECTOR
A connector is a removable connection between two or more electrical wires or components. The female contacts are on one side and the male contacts on the other side. This way they can be connected and disconnected. The connector should protect the contacts against unwanted electrical connections and external influences. It also ensures the proper connection of the applicable contacts.

1.2 CONTACT
A connector has one or more contacts. These contacts are available in various sizes and models. However, they all have the same design:
The mating part (1) enables the electrical connection between the contacts. The contact press part (2) is the electrical connection between the stripped part of the wire and the contact. The relief part (or pull relief) (3) relieves the contact press part from mechanical wear. The insulation relief is placed over the insulating sheath and/or the SCAT.
With contacts, three dimensions are important: the diameter (1) of the wire to be connected, the size of the contact press part (2), which is linked to the wire diameter, and the size of the mating part (3).

2.1 REMOVAL AND INSTALLATION, CONNECTORS
Unlocking the connectors
The connectors can often be locked with one another or with a component. They can be divided into:
A. Active locking.
This means that the lock must be activated. With this type a lock must often be pressed.
B. Passive locking.
Opens when the parts are pulled apart with a certain force.
Two connectors in one housing
These connectors consist of two separate connectors. To remove the contacts first remove the connectors from the connector housing. Push the locking lip aside before removal. The connector can then be slid out of the connector housing.

2.2 REMOVAL AND INSTALLATION, CONTACTS
Contact lock
There are various types of contact locks. A few examples are given below. When a lock is applied, individually for each contact, this is called a primary lock. An extra general lock for several contacts in a connector is a secondary lock.
Primary contact lock
To keep an individual contact in the connector in place, a contact is often furnished with one or more locking bolts. This is a primary lock. These locking bolts should never be damaged, with a view to pressing and ejecting the contacts.
E501481
Secondary contact lock
This type of lock is normally used on 2 and 3-row connectors. For connectors (1) with a locking lip (2) first remove the lip before removing the contacts. This is a secondary lock. The locking lip is on the side of the connector and can usually be recognised from a colour that is different from the colour of the connector. The lip is removed entirely. Now the contacts can be removed using the proper ejector tool by unlocking the primary lock.
Examples:
- Cab connectors
- Electronic unit connectors

The contacts may also be locked secondarily by the lower part of the connector. After tilting this lower part, the contacts can be removed by unlocking the primary lock using the proper ejector tool. This type of lock is used only on 2-row connectors.
Examples:
- MTCO connector
E501497
A different type of secondary lock is formed by two sliding parts of the connector. The upper half (on the wire insert side) and the lower half form the extra contact lock.
To unlock this secondary contact lock the upper half of the connector must be pushed away slightly in the direction of the arrows on the connector housing. The contacts can then be removed from the connector using the proper ejector tool.
After any installation of wires with contacts, the connector must be pressed into the lock again. If this is not done it will not fit into the counterpart.

2.3 FITTING CONTACTS TO ELECTRICAL WIRES
The increasing application of electronics in vehicles means a much broader range of connectors, contacts and wiring is being used. The result of this is that more attention has to be paid to making and repairing connections. The following criteria should be taken into account:
1. Wires with a reduced insulation thickness,
with retention of the mechanical properties, for use with core sections from 0.5 to
2.5 mm
2. Wires with a normal insulation thickness, for
use with core sections from 4 to 120 mm
3. Wires for various temperature ranges:
T1: from --40_Cto+70_C (in cab and chassis) and T2: from --40_C to +100_C (in engine compartment and gearbox)
Note:
In view of the mechanical strength required, the minimum permissible core section is 1 mm with the exception of cab wiring. At certain points this may be 0.5 mm

To ensure the reliability of systems and connections, the following points should be observed when repairs or extensions are made to the wiring:
A. Always choose the following:
- the correct type of contact
- the correct wire diameter for the contact used
- the correct type of contact material (tin-plated, silver-plated or gold-plated)
B. Use the right tool for the job. Wire ends are
always clamped to a contact. Special crimping tools have been developed for this purpose.
Note:
Connections will only be reliable if these crimping tools are used and the contact is fitted in the correct hole.
C. Strip the correct length of wire. Always use
stripping pliers. Theruleofthumbis: stripped length = length of shrink-sleeve + 1 mm.

Make sure that the core is not damaged during stripping or problems may occur a fter some time.
Note:
A good connection will only be obtained if points A, B and C are complied with. This implies that both the copper core and the insulation are firmly clamped in place.

Insulation connection
Different types of crimping are allowed:
1. Normal crimping; the two sides of the relief part fully engage the insulation.
2. Double crimping; two wires are clamped in one contact.
3. Overlap crimping; the two sides of the relief part engage one another slightly.
4. Double overlap crimping; two wires are clamped in one contact, the two sides of the relief part engaging one another slightly.
A. If the insulation connection is correct, the
wire is clamped in the relief part with the correct pressure and the insulation is not broken.
B. If the contact pressure is too high the
insulation could break, possibly causing a short circuit. This may for instance be caused by:
- using the wrong crimping tool
- using an improper hole in the crimping
tool (too small)
- a defect in the crimping tool delaying
the interruption of the contact pressing.
C. If the contact pressure is not sufficient the
insulation may not be clamped and the wire may come loose. This will interrupt the electrical connection but may also result in a short circuit. This may for instance be caused by:
- using the wrong crimping tool
- using an improper hole in the crimping
tool (too big)
- interrupting the contact pressing
prematurely.

2.4 FITTING A SCAT SEAL
SCATs are used in places where wires are exposed to heavy conditions (environment or application of the vehicle), with the risk of water entering the connector.
The SCAT seal, which is made of silicone, prevents corrosion inside the connector and keeps the seal properties intact in the event of temperature changes.
The SCAT seal is pressed around the wire with the relief part of the contact.
The SCATs are available in various colours and sizes.
1. Select the right SCAT for the wire, contact and connector.
2. Slide the SCAT onto an unstripped wire (A).
3. Slide the SCAT far enough onto the wire and strip the wire to the proper length (B).
4. Slide the SCAT back to the tip of the stripped wire so that the copper just sticks out of the SCAT (C).
5. Place the contact in the proper manner (D) around the SCAT (2) and the stripped wire (1).
6. Now crimp the contact around the SCAT and the wire using the proper crimping tool.

2.5 FITTING AN ELECTRICAL BUFFER CONNECTION
A buffer connection is made when at least two wire ends must be connected to one another. This may be required because of a wire repair or if a wire is to be added to a connection.
Note:
When adding a new wire to an existing wire, both wires must be of the same thickness. If part of the existing wire is to be removed, try to make sure that the wire number can still easily be found on the wire.
3
The contact crimping part (1) is the electrical connection to the stripped wire part. The central stop (2) is a limiter, preventing the wire to be connected from being inserted too far. The insulation is a crimp insulating sleeve with glue layer (3), which, after heating by a blow drier, will offer protection against unwanted electrical contact and corrosion.
There are three different buffer connectors available: red, blue and yellow. Depending on the wire thicknesses to be connected (and possibly the number of wires to be connected) a specific colour must be used.
- red diameter 0.25 - 0.75 mm
- blue diameter 1.0 - 2.5 mm
- yellow diameter 4.0 - 6.0 mm
Connecting more than two wires to one another is not recommended. The glue layer of the crimping insulation is not sufficient to seal all resulting gaps. So this is certainly not permitted outside the cab.

It is very important to carry out contact crimping in the correct way to prevent electrical faults. For cold fusion a contact crimping tool is required. This tool creates a cold fusion between wire and buffer connector.
E501491
Fitting the contact crimp connector
1. Select the right buffer connector for the wires to be connected.
Note:
Ifthreewiresofthesamediameterhavetobe connected after all, choose a buffer connector that is the same diameter as two of the wires. The single wire on the other side must be stripped to double length and folded double. Thesameapplieswhenawireisusedonone side that is twice the diameter of the other.
3
2. Strip the wire to a length of 4 to 5 mm.
Note:
The stripped wire end may not be twisted.
3. Choose the proper contact crimping tool on the basis of the buffer connector and wire diameter, and check the holes to be used.
4. Place the buffer connector in the hole of the tool and clamp it gently so the buffer connector will remain in the hole.
5. Slide the stripped wire ends into the side of the buffer connector that is engaged by the contact crimping tool.
Note:
The wire insulation may not be slid into the contact part of the buffer connector.

6. Compress the contact crimping tool: Do not interrupt the contact crimping before the tool is completely compressed to the end position. Only then is full contact crimping completed and the tool can be opened.
7. Repeat this for the other ends of the buffer connector.
8. Check the contact crimping for damage and pull the wires to ensure they are properly fixed.
Note:
Improper contact crimping means a bad connection, which may cause failures.
Avoid breathing in the vapours produced when heating the crimping insulation.
9. Heat the crimping insulation to fix it properly to the wire insulation. Ensure that the insulation does not get burnt. If the insulation gets burnt it will become brittle and easily break or crack.

2.6 REMOVAL AND INSTALLATION, EARTH WIRE
When a failure occurs in an electrical system, one of the first things to be checked is the earth connection, with particular attention being paid to earth connections on the chassis.
Points for special attention when checking earth connection on chassis
If an earth connection has been removed and is being re-installed, pay attention to the following:
- The bolt, nut, earth strip and washers must be cleaned (e.g. using a steel brush or sand paper). If a component is corroded, it must be replaced by a new one.
- Clean all dirt and paint from the area around the engine/chassis earth connection on both sides of the chassis member so that the bare metal is visible.
- Clean all dirt and paint from the area around the battery/chassis earth connection on the inside of the chassis member so that the bare metal is visible.
- On the earth strip side, the cleaned area must be larger than the contact area of the earth strip.
E501495
3
- On the nut side, the cleaned area must be larger than the contact surface of the nut.
- After fitting the earth connection, a protective zinc primer should be applied to both sides of it and it should be painted.

2.7 REPAIRING CAN NETWORK WIRING
When repairing or replacing the CAN wiring, the original twisted lengths and diameters of the wiring must be taken into consideration. A 10% tolerance in the twisted length of the wiring is permitted. Winding density 40-50 turns/m.
3
When repairing the wiring, the winding density must be maintained, with the provision that it is permissible for the wiring at the point of repair to have no twists over a maximum length of 60 mm. When the wiring is being repaired, it must be secured in a wire tie at the end and in the middle.
Replacing CAN wire
1. Measure the length of the original wire when untwisted.
2. Measure the diameter of the original wire. Always take a wire of the same diameter or, if this is not available, of the next size.
3. Preferably choose a wire of the same colour as the original wire.
4. Follow the routing of the original wire and install the wire in the original way.

1. SAFETY INSTRUCTIONS
1.1 BATTERIES
- The sulphuric acid in the batteries is an aggressive and poisonous liquid. While working on batteries, wear protective clothing, gloves and safety goggles. In case of contact with clothes, skin or eyes, wash immediately with copious amounts of water. Consult a doctor in case of contact with the eyes or skin.
- Always remove the earth lead first before working on batteries. When connecting battery leads, always connect the earth lead last.
- Always handle batteries carefully and hold them upright.
- When topping up batteries, never allow the electrolyte level to rise more than 10 mm above the plates or above the level indicator.
- Never put tools or other materials, which could accidentally short circuit the battery poles, down on the batteries or in the vicinity of batteries. Short-circuited battery poles may cause the battery to explode.
- Secure the batteries well after completing the work, but not too tightly.

1.2 BATTERY CHARGING
- An explosive gas mixture may be released during battery charging. Only charge batteries in a well-ventilated area.
- Never smoke or allow naked flames or sparks in the vicinity of the battery.
- Allow frozen batteries to thaw before charging.
- Switch the charger off before the leads to the battery are disconnected.

2. CHARGING BATTERIES
2.1 GENERAL
- A battery may only be charged using DC current. Connect the positive pole of the battery to the positive terminal (+) of the charger, and the negative pole of the battery to the negative terminal (--) of the charger. The cell sealing plugs may remain on the battery during charging (with the exception of fast charging). The cell voltage will rise during charging. This increase in voltage depends on the charging current applied and the temperature. During normal charging, the cell voltage will rise from about 2 volts/cell to about 2.65 volts/cell. If a charging voltage of about 2.35 to 2.4 volts/cell (about 14.2 volts in a 12V battery) is exceeded, this will initiate active gas development. As a consequence of the rise in voltage during charging, the charging current will gradually fall, as a rule. Overcharging will reduce the service life of a battery.
4
- If the charging of the battery is continued after it has been fully charged (even with a low current), this will lead to corrosion (corrosive attack) of the grids of the positive battery plates. This type of wear leads to premature redundancy of the battery. Depending on the capacity of the charger, the normal charging time is between 8 and 15 hours. If during charging, the temperature of the battery acid exceeds 55_C, charging should be stopped. High temperatures reduce the service life of the battery.

Charging batteries CF65/75/85 series 0E621376
- A battery should be considered to be charged when the charge voltage stops rising for a period 2 hours and the acid density (relative density) has reached the nominal value (for example 1.28 kg/dm and it rises no further.
- A charged battery must be used immediately. If this is not possible, maintain the battery as described in the “Storage of batteries” section.
- A discharged battery must be charged as soon as possible. If a discharged battery is not recharged, the battery plates may become sulphated (i.e. they may become hard), which will lead to permanent loss of capacity.

- Never disconnect the battery terminals when the engine is running to prevent damage to electronic components.
- Connect the positive lead (+) of the battery charger to the positive terminal (+) of the battery first and then the negative lead (--) to the negative terminal (--).
- Switch off the battery charger before disconnecting the battery charger leads, to avoid sparking and to eliminate the risk of explosion.
- To disconnect, release the negative terminal (--) first and then the positive terminal (+).

2.2 METHODS OF CHARGING
Always disconnect the battery terminals before charging.
Normal charging
- Normal charging is done to partially or fully restore discharged batteries to full capacity. In most cases, a charging current of
1
/10of the capacity is selected.
- It is important to reduce the charging current during gas development and to switch the charger off when the battery is charged.
Fast charging
- With this method, multiples of the normal charge current (approx. 3 to 5 times) are used to achieve an acceptable charge condition in the shortest possible time.
1
/20to
4
- Before fast charging, remove the battery leads to prevent damage to the electronic components.
- Remove the cell sealing plugs so that the released gases can easily escape.
- To prevent overcharging, switch to a lower charging current when the cell voltage is reached (2.35 to 2.4 volts/cell).
Note:
If possible, avoid fast charging. Only use it in exceptional cases. Fast charging causes battery overloading, which reduces the service life of the battery.

Charging batteries CF65/75/85 series 0E621376
Buffer charging
- With this method, the consumer and the charger are both connected to the battery. The charger delivers sufficient current to ensure that the battery remains virtually fully charged. The battery will deliver peak currents to the consumer.
- Buffer charging is best done at a constant (stabilised) voltage.
Trickle charging
- A fully charged battery that is not used for some time, will start to discharge of its own accord. It may discharge at a rate of 0.1% to 1% per day. Trickle charging compensates for such discharges.
- The charging current for trickle charging should be around 0.1 A per 100 Ah.

3. STORAGE OF BATTERIES
3.1 GENERAL
Before storing batteries, take the following steps:
1. Remove the battery terminals.
2. Clean the battery terminals and top of the batteries.
3. Grease the battery terminals with petroleum jelly.
4. Check the charging condition of the batteries, and charge them if necessary. See section “Checking batteries”.
5. Check the electrolyte level; this should be approx. 10 mm above the plates or up to the level indicator, if present. If necessary, top the batteries up with distilled water.
4
3.2 STORAGE UP TO FOUR WEEKS.
If batteries (whether as separate units or fitted in a vehicle) are not going to be used for an extended period of time not exceeding four weeks, the following measures should be taken:
1. Do not connect the battery leads to the batteries.
2. Check the charging condition of the batteries regularly, particularly if the batteries are stored in low temperature conditions. See section “Checking batteries”. If the voltage falls below 12.4 volts, or if the relative density of the electrolyte in one or more of the cells is less than 1.23 kg/dm the battery must be charged.
Note:
The lower the relative density of the electrolyte, the higher the risk of the battery freezing.

1. Remove the batteries from the vehicle and store them in a frost-free, dry, cool and well-ventilated room.
2. Check the charging of the batteries regularly, at least once every four weeks. See section “Checking batteries”. If the voltage falls below 12.4 volts, or if the relative density of the electrolyte in one or more of the cells is less than 1.23 kg/dm the battery must be charged.
3. Limit the storage period to a maximum of three months. The longer the period of storage, the greater the permanent loss of capacity.

4. CHECKING BATTERIES
4.1 VISUAL INSPECTION
- A white dividing line at1/3of the plate height (this can be seen through transparent battery boxes) indicates that the battery has been left in a deeply discharged condition.
- If the electrolyte is brown and the battery consumes a lot of fluid, this indicates that the battery is overcharged.
- If the electrolyte is turbid and milky and the cells have a white deposit, the battery has become damaged due to insufficient charging (deep discharge).
4.2 CHECKING THE CHARGING CONDITION
Relative density
- The charging and discharging of the battery leads to a chemical reaction in the battery, which involves sulphuric acid. The sulphuric acid concentration drops as the battery discharges. The concentration, measured as relative density (kg/dm determining the charging condition of the battery.
- An acidimeter can be used to check the charging condition.
Relative density at 27_C in kg/dm Charged battery : 1.28 Half-charged battery : 1.20 Discharged battery : 1.10
- Measurement corrections are necessary if temperatures are significantly lower or higher. For every 10_C lower temperature, subtract 0.007 points from the measured value. For every 10_C higher temperature, add 0.007 points. In batteries that are in good condition, the relative density should be the same in all the cells. The difference between the highest and lowest relative density must not exceed 0.03 kg/dm

Note:
If the relative density in one of the cells is much lower than in the other cells it may be caused by cell closure. If the relative relative density of two adjacent cells is much lower than in the other cells, this indicates a leakage in the cell partition. In both cases, the battery must be replaced.
Voltage
- The charging condition of the batteries can be measured using a sensitive, preferably digital voltmeter. This method can only be used 1 to 2 hours after full completion of charging or discharging. Measure the absolute rest voltage (the positive and negative terminals of the battery must be removed). The charging condition of the battery can be calculated using the formula: Voltage per cell = relative density (kg/dm
For example: For a fully charged battery, the relative density per cell is 1.28 kg/dm per cell is therefore 1.28 + 0.84 = 2.12 V. A 12V battery has 6 cells. The total voltage for a charged battery is 6 x 2.12 = 12.72 V. The voltage of a half-charged battery is approx. 12.24 V. The voltage of a discharged battery is approx. 11.75 V.

4.3 CHECKING USING A BATTERY TESTER
- The general condition of the battery can be checked quickly using a battery tester. For this check, a load is applied to the battery, and then the discharge voltage at the battery terminals is measured. The load applied to the battery must be at least 3 times the capacity of the battery.
- As a rule, the test can be carried out when the battery is sufficiently charged (relative density 1.25 - 1.28 kg/dm At normal temperatures (10-20_C), the charging voltage for a properly charged battery must be 10 volts after 10 seconds. In the case of a partially discharged battery (relative density 1.25 kg/dm should be at least 9 volts. It is important that the voltage is measured directly at the battery poles.
