BATTERY INSPECTION
M!XEl8N
BATTERY VISUAL INSPECTION (1)
The battery contains a visual test indicator which gives blue
signal when an adequate charge level exists, and white signal
when charging is required.
BATTERY VISUAL INSPECTION (2)
Make sure ignition switch is in Off position and all battery feed
accessories are Off.
1.
Disconnect ground cable from battery before disconnecting
(+)
cable.
2. Remove battery from vehicle.
Caution
Care should be taken in the event battery case is
cracked or leaking to protect hands from the electrolyte. A suitable pair of rubber gloves
(not
the household type) should be worn when removing battery by
hand.
3.
Inspect battery carrier for damage caused by loss of acid
from battery. If acid damage is present, it will be necessary
to clean area with a solution of clean warm water and
baking soda. Scrub area with a stiff bristle brush and wipe
off with a cloth moistened with ammonia or baking soda in
water.
4. Clean top of battery with same solutions as described in
Step (3).
5. Inspect battery case and cover for cracks. If cracks are
present, battery must be replaced.
6.
Clean the battery post with a suitable battery post cleaning
tool.
7. Clean the inside surfaces of the terminal clamps with a
suitable battery terminal cleaning tool. Replace damaged or
frayed cables and broken terminals clamps.
8. Install the battery in vehicle.
9. Connect (+) and
(-)
cables to battery in the order of
mention.
IO.
Tighten the clamp nut securely.

Note
The temperature is an ambient temperature of the battery

BA-ITERY
CHARGING
MYEICL
Caution
When batteries are being charged, an explosive
gas forms beneath the cover of each cell. Do not
smoke near batteries on charge or which have
recently been charged.
Do not break live circuits at the terminals of the
batteries on charge. A spark will occur where the
live circuit is broken.
Keep all open flames away from the battery.
Battery electrolyte temperature may temporarily be
allowed to rise to
55OC
(131
OF).
Increase of
electrolyte temperature above
55OC
(131 “F) is
harmful to the battery, causing deformation of battery
cell, decrease in life of battery, etc.
CHARGE RATE
If the test indicator is white, the battery should be
charged as outlined below.
OPEN CIRCUIT VOLTAGE TEST
(3)
1. Turn headlights on for 15 seconds.
2.
Turn headlights off for 2 minutes to allow battery
voltage to stabilize.
3. Disconnect cables.
4. Read open circuit voltage.
5. If the open circuit voltage is under 12.4 volts,
charge the battery. (See BATTERY CHARGING)
LOAD TEST
(4)
1. Connect a load tester to the battery.
2. Load the battery at 15 amps for 15 seconds to
remove surface charge.
3. Load the battery at the recommended discharge
rate. (See LOAD TEST RATE CHART)
4. Read voltage after 15 seconds and then remove
the load.
5. If the voltage is not maintained at the minimum
voltage in the LOAD TEST CHART throughout the
test, the battery should be replaced.
TSB Revision
When the dot appears or when maximum charge
shown below is reached, charging should be
stopped.
NOTE
When the charging is performed at 5 amps,
charging is virtually
loo:!
three hours after the
indicator’s indication changes from white to blue.
Use fast charging only in an emergency.
If the indicator does not turn to blue even after the
battery is charged, the battery should be replaced;
do not overcharge.

l When the engine coolant temperature is high,
the
unit’s
resistance is low and there is a great
flow of current in the circuit, so the gauge’s
indicator indicates in the “H” area.
l When the engine coolant temperature is low,
the unit’s resistance is high and there is a small
flow of current in the circuit, so the gauge’s
indicator indicates in the “C” area.
<Reed switch>
l Pulses are produced in accordance with the
vehicle speed, and vehicle-speed signals are
input to systems (the transaxle-control system,
etc.) that regulate according to the vehicle
speed.
NOTE
For operation of warning light and indicator light,
refer to
P.54-36.
3. Systems dependent upon control according to
the vehicle speed do not function correctly.
l Check the reed switch (located within the
speedometer).
4. The meter illumination light does not illuminate.
(1)
The tail lights illuminate.
l Check the rheostat.

OPERATION
<Fuel gauge>
l When the ignition key is at the “ON” position,
the fuel gauge is activated.
l
When there is much fuel, the unit’s resistance is
small and the current flowing in the circuit is
great, so the gauge’s indicator indicates in the
“F” area.
l
When there is little fuel, the unit’s resistance is
high and the current flowing in the circuit is
small, so the gauge’s indicator indicates in the
“E” area.
<Engine coolant temperature gauge>
l When the ignition key is at the “ON” position,
the engine coolant temperature gauge is activated.
TROUBLESHOOTING HINTS
1. The fuel gauge doesn’t function, or shows the
incorrect indication.
(1) Disconnect the connector of the fuel gauge
unit; the “F” side is indicated when terminal
3 (FWD) or 2 (AWD) is then grounded.
l Check the fuel gauge.
2. The engine coolant temperature gauge doesn’t
function, or shows the incorrect indication.
(1) The “H” side is indicated when the connec-
tor of the engine coolant temperature gauge
unit is disconnected and then grounded.
l Check the engine coolant temperature
gauge unit.

NOTE
For AWD models, refer to the section concerning special
handling instructions for AWD models in GROUP 00.
Take note of the following before inspection:
(1) Assure tire pressure at standard value.
(Refer to GROUP 31 -Specifications.)
(2)
When placing the vehicle on a speedometer tester drum,
make sure the center line of the vehicle is at right angles to
the center line of the drum. Also, make sure the drum is
positioned so as to center between the front tires.
Rear wheel safety procedures
(1)
Be sure to chock both rear wheels to prevent the vehicle
from moving. Secure the stoppers to the floor, or take
measures to prevent the stoppers from slipping.
(2) Make sure the parking brake has been set.
Front wheel away prevention procedure
(1)
Attach tension bars to the front traction hook. Secure the
ends of both bars to anchor plates.
(2) Make sure the tension on the right and left bars is the
same. Also be sure there is enough tension on each bar.
Accident prevention procedures
(1)
Attach a chain or wire to the rear traction hook. Make sure
the end of the wire or chain is secured firmly.
(2)
Take all other necessary precautions.
Use a speedometer tester to measure the speedometer’s
indication error.

Caution
As the tachometer is negative grounded, do not connect
battery conversely to prevent damaging transistor and
diode.
Connect the engine speedometer.
(1) Insert the paper clip from behind the connector.
Caution
Insert the paper clip parallel to the terminal surface as
shown in the figure at left.
(2)
Connect the engine speedometer to the inserted clip.
NOTE (From 1990 models <DOHC>)
For
rpm.
one-half of the actual engine rpm is indicated, so
the actual engine rpm is two times the indicated value
shown by the tachometer.
