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 CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit according to the manufactuer’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 generator
and connect the wire to the negative (

Standard amperage: 10 A or less
Standard voltage:
At 25
° C (77 ° F): 14.0 − 15.0 V
At 115 ° C (239 ° F): 13.5 − 14.3 V
If the voltage reading is greater than the standard voltage, re-
