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
			1
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).

DIAGNOSTICS	5
Fault finding	CF65/75/85 Series ≥0E621376
1.1 SHORT CIRCUITS

A short circuit is caused by a positive wire shorting to earth somewhere. In most cases this will cause a fuse to blow.

1To 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.	W 5 03 013

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.

5	DIAGNOSTICS
CF65/75/85 Series ≥0E621376	Fault finding
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.

1A poor earth connection of the main earth circuit (2) between cab and chassis may result in a current through the steering shaft (1).

1

E502316

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.

1.Open the grille.

2.	Switch on vehicle ignition and as many
	consumers as possible, e.g.:		1
	-	dipped beam		1
	- 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:

4bulkhead lead-through connector

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

1without 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. GENERAL

1.1 MULTIMETER

Various measurement options can be selected on the Fluke 87 multimeter.

Units of measurement

The multimeter should be set to the range for the unit of measurement required.

For example, voltage range, current range, or resistance range.

The units of measurement are indicated by symbols on the meter. The following symbols are used:

1.DC voltage

2.AC voltage

3.DC current

4.AC current

5.Resistance

6.Duty cycle

7.Frequency

1.2 SCOPEMETER

Diagnostics in modern electronic systems is becoming steadily more complex.

Using a multimeter on its own is not always sufficient to diagnose a fault.

The scopemeter allows complex signals to be measured.

2Practical examples of complex signals are:

-PWM signals

-signal deformation

-CAN-bus-signals
