2. INSPECT BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Visually check the battery terminals.
(1) Check that the battery terminals are not loosened or corroded.
(b) Visually check the fusible link and fuses.
(1) Check that there is continuity of the fusible links, high−current fuses and regular fuses.
3. INSPECT V−RIBBED BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
SIf any defects are found, replace the v−ribbed belt.
SCracks on the rib side of the belt are considered ac-
ceptable.
If the belt has chunks missing from the ribs, it should
be replaced.
(b) Check that the belt fits properly in the ribbed grooves.
Confirm that the belt has not slipped out of the groove on the
bottom of the pulley by hand.
4. VISUALLY CHECK GENERATOR WIRING
(a) Check that the wiring is in good condition.
5. LISTEN FOR ABNORMAL NOISES FROM GENERATOR

(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.
