(a) Turn the ignition switch ON. Check that the charge warning light comes on.
(b) Start the engine, then check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warning light circuit.
7. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) If a tester is not available, connect a voltmeter to the
charging circuit as follows:
(1) Disconnect the wire from terminal B of the genera-
tor, then connect it to the negative (−) lead of the
ammeter.
(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, then check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 12.9 to 14.9 V
8. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn the high beam headlights ON and turn the heater blower
switch to the ”HI” position.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
SIf the ammeter reading is less than the standard amperage, repair the generator.
SIf the battery is fully charged, the indication will sometimes be less than the standard amperage.
