(b) Check that it fits properly in the ribbed grooves.
HINT:
Check with your hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
5. VISUALLY CHECK GENERATOR WIRING
(a) Check that the wiring is in good condition.
6. LISTEN FOR ABNORMAL NOISES FROM GENERATOR
(a) Check that there is no abnormal noise from the generator while the engin\
e is running.
7. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ON. Check that the charge warning light comes on\
.
(b) Start the engine and check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warn\
ing light circuit. 8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) According to the following procedure, connect an amme-ter and voltmeter as shown in the illustration.
(1) Disconnect the wire from terminal B of the generatorand connect it to the negative (±) lead of the amme-
ter.
(2) Connect the positive (+) lead of the ammeter to ter- minal B of the generator
(3) Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
(4) Ground the negative (±) lead of the voltmeter.
(b) Check the charging circuit. (1) Keep the engine speed at 2,000 rpm, check thereading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 12.9 to 14.9 V
HINT:

If the voltmeter reading is more than standard voltage, re-
place the voltage regulator.

If the voltmeter reading is less than the standard voltage,
check the voltage regulator and generator as follows:
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) Keep the engine speed at 2,000 rpm, turn on the high beam headlights and\
turn the heater blower switch to the ºHIº position.
(b) Check the reading on the ammeter. Standard amperage: 30 A or more
HINT:

If the ammeter reading is less than standard amperage, repair the genera\
tor.

If the battery is fully charged, the indication will sometimes be less t\
han standard amperage.
