CHARGING SYSTEM
ON−VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL AND VOLT-
AGE
(a) Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled wa-
ter if possible). check the charging system.
(b) Measure the battery voltage between the negative ( −)
and positive (+) terminals of the battery.
Standard voltage: At 20° C (68°F): 12.7 − 12.9 V
HINT:
Before measuring the voltage, turn the ignition switch
OFF and turn off the electrical systems (headlight, blower
motor, rear defogger etc.).
If the vehicle has been running, wait 20 minutes or more
after the vehicle stops before measuring the battery volt-
age.
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
2. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loose or cor-
roded.

If the light does not operate as specified, troubleshoot the dis-
charge warning light circuit.
6. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per the 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 generator
and connect it to the negative ( −) lead of the amme-
ter.
Connect the positive (+) lead of the ammeter to ter-
minal B of the generator.
Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
Ground the negative ( −) lead of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idle to 2,000 rpm, check the
reading on the ammeter and voltmeter.
Standard amperage 10 A or less
Standard voltage:
at 25° C ’(77°F)14.0 − 15.0 V
at 115°C ’(239° F)13.5 − 14.3 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than the 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.
7. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
”HI”.

(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than standard amperage, repair
the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.
