6. REMOVE ENGINE UNDER COVER
7. VISUALLY CHECK GENERATOR WIRING AND LIS-
TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
8. CHECK CHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Switch off all accessories.
(c) Turn the ignition switch ON, and check that the charge
warning light is lit.

HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per manufacturer's instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
S
Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (−) tester probe
of the ammeter.
S
Connect the positive (+) tester probe of the amme-
ter to terminal B of the generator.
S
Connect the positive (+) tester probe of the voltme-
ter to terminal B of the generator.
S
Ground the negative (−) tester probe of the voltme-
ter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.2 − 14.8 V
