ON-VEHICLE INSPECTION
CAUTION:
z
Check that the battery cables are connected to the
correct terminals.
z
Disconnect the battery cables when the battery is given a quick charge.
z
Do not perform tests with a high voltage insulation resistance tester.
z
Never disconnect the battery while the engine is running.1.
CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte quantity of each cell (MaintenanceFree Battery).
If under the lower level, replace the battery (or add distilled water if possible) and check the charging system.
(b) Check the electrolyte quantity of each cell (Except Maintenance-Free Battery).
If under the lower level, add distilled water.
2.
CHECK BATTERY SPECIFIC GRAVITY(Except Maintenance-Free Battery)
(a) Check the specific gravity of each cell.
Standard specific gravity: 1.25 to 1.29 at 20_C (68_F)
HINT:
If the specific gravity is less than specification, charge the battery.

CHECK BATTERY VOLTAGE
After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the engine, turnthe ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
Turn the ignition switch OFF and turn off the electrical systems.
Measure the battery voltage between the negative (-)
and positive (+) terminals of the battery.
Standard voltage: 12.5 to 12.9 V at 20_C (68_F)

HINT:
If the voltage is lessthan specification, charge the battery.

(d) Check the indicator as shown in the illustration.
HINT:
z
Blue: OK
z
White: Charging Necessary
z
Red: Insufficient Water
4.
CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or corroded.
(b) Check thefusible link, H-fuses and fuses for continuity.
5.
INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
HINT:
z
If any defect has been found, replace the drive belt.
z
Cracks on the rib side of a belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be
replaced.

(b) Check that it fits properly in theribbed grooves.
HINT:
Check with your hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
6.
VISUALLY CHECK GENERATOR WIRING
(a) Check that the wiring is in good condition.
7.
LISTEN FOR ABNORMAL NOISES FROM GENERATOR
(a) Check that there is no abnormal noise from the generator
while the engine is running.
8.
INSPECT CHARGE WARNING LIGHT CIRCUIT(a) Turn the ignition switch ON. Check that the charge warning light comes on.
(b) Start the engine. Check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the
charge warning light circuit.
9.
INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) If a battery/generator tester is available, connect the tester to the charging circuit as per manufacturer’sinstructions.

If a tester is not available, connect a voltmeter to the
charging circuit as follows.
(1) Disconnect to the wire from terminal B of the generator and connect it to the negative (-) lead of the
ammeter.(2) Connect the positive (+) lead of the ammeter to terminal B of the generator.
(3) Connect the positive (+) lead of the voltmeter to terminal B of the generator.
(4) Ground the negative (-) lead of the voltmeter.
Check the charging circuit.
(1) With the engine running from idle to 2,000 rpm,
check the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
