If the voltmeter reading is less than 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.

If 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.
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
ºHIº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.

INSPECTION
1. INSPECT ROTOR
(a) Check the rotor for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the slip rings.
Standard resistance: 2.7 ± 3.1 W at 20°C (68°F)
If there is no continuity, replace the rotor.
(b) Check the rotor for ground.
Using an ohmmeter, check that there is no continuity be-
tween the slip ring and rotor.
If there is continuity, replace the rotor.
(c) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(d) Using vernier calipers, measure the slip ring diameter.
Standard diameter: 14.2 ± 14.4 mm (0.559 ± 0.567 in.)
Minimum diameter: 12.8 mm (0.504 in.)
If the diameter is less than minimum, replace the rotor.
2. INSPECT STATOR (DRIVE END FRAME)
(a) Check the stator for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the coil leads.
If there is no continuity, replace the drive end frame assembly.
(b) Check the stator for ground.
Using an ohmmeter, check that there is no continuity be-
tween the coil lead and drive end frame.
If there is continuity, replace the drive end frame assembly.

3. INSPECT BRUSHES
Using vernier calipers, measure the exposed brush length.
Standard exposed length: 10.5 mm (0.413 in.)
Minimum exposed length: 1.5 mm (0.059 in.)
If the exposed length is less than minimum, replace the brush
holder assembly.
4. INSPECT RECTIFIERS (RECTIFIRE HOLDER)
(a) Check the positive (+) rectifire.
(1) Using an ohmmeter, connect one tester probe to the
positive (+) terminal and the other to each rectifier
terminal.
(2) Reverse the polarity of the tester probes and repeat
step (a).
(3) Check that one shows continuity and the other
shows no continuity.
If continuity is not as specified, replace the rectifier holder.
(b) Check the negative (±) rectifire.
(1) Using an ohmmeter, connect one tester probe to
each negative (±) terminal and the other to each
rectifier terminal.
(2) Reverse the polarity of the tester probes and repeat
step (a).
(3) Check that one shows continuity and the other
shows no continuity.
If continuity is not as specified, replace the rectifier holder.
5. INSPECT BEARING
Check the bearing is not rough or worn.
If necessary, replace the bearing. (See page CH±11)
