ON-VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance-Free Battery:
If under the lower level, replace the battery (or add distilled wa-
ter if possible). Check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity: 1.25 - 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance-Free Battery:
CHECK BATTERY POSITIVE VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery positive voltage between the nega-
tive (-) and positive (+) terminals of the battery.
Standard voltage: 12.5 - 12.9 V at 20°C (68°F)
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS AND FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
If the terminals are corroded, clean the terminals.
(b) Check the fuses for continuity.

7. VISUALLY CHECK GENERATOR WIRING AND
LISTEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
8. CHECK CHARGE WARNING LIGHT CIRCUIT

(b) Turn off all accessories.
(c) Turn the ignition switch ºONº. Check that the charge warn-
ing light is lit.
(d) Start the engine. Check that the light goes off.
If the light does not go off as specified, troubleshoot the charge
light circuit.
9. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per manufacturer's instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (-) probe of the
ammeter.
Connect the positive (+) probe of the ammeter to
terminal B of the generator.
Connect the positive (+) probe of the voltmeter to
terminal B of the generator.
Ground the negative (-) probe of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.2 - 14.8 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than standard voltage, check the
voltage regulator and generator as follows:
With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.
If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.
If the voltmeter reading is less than standard volt-
age, check the generator.
