HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as permanufacturer's instructions.
(a) lf a tester is not available, connect a voltmeter to the
charging circuit as follows:
•
Disconnect to the wire from terminal B of the gener­
ator and connect it to the negative (-) lead of the
ammeter.
•
Connect the positive (+) lead of the ammeter to ter�
mina! 8 of the generator.
Connect the positive (+) lead of the voltmeter to ter­
minal B of the generator.
•
Ground the negative (-) lead of the voltmeter.
Check the charging circuit as follows:
(b)
With the engine running from idle to 2,000 rpm, check the
reading on the ammeter and voltmeter.

Standard amperage: 1 OA or less
Standard voltage: 13.2 - 1 4.8 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than the standard voltage, check
the voltage regulator and generator as follows:
•
With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.
Jt the voltmeter reading is more than standard volt­
age, replace the voltage regulator.
•
If the voltmeter reading is less than standard volt�
age, check the generator.

Standard amperage: 30 A or more
If the ammeter reading is less than standard amperage, repair
the generator.

If the battery is fully charged, the indication will sometimes be
Jess than standard amperage_
