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.

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 "HI" position.
(b)
Check the reading on the ammeter.
Standard amperage: 30 A or more
HINT:
Y
If the ammeter reading is less than standard amperage, repair the generator.

Check that it fits properly in the ribbed grooves.
INSPECT CHARGING CIRCUIT WITHOUT LOAD
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 generator
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.
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
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:
