(b) Start the engine and check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warning 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.

and 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 the
reading 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.
