When measuring the voltage, however, turn the ignition
switch OFF and turn off the electrical systems.
If the voltage is less than the specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.
5. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
HINT:
Cracks on the ribbed side of the belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be re-
placed.
(b) Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
Nippondenso BTG 20 (95506−00020) or
Borroughs No. BT−33−73F
Drive belt tension:
New belt: 160 ± 20 lbf
Used belt: 100 ± 20 lbf
If necessary, adjust the drive belt tension.

HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing the drive belt, check that it fits properly in
the ribbed grooves. Check with your hand to confirm that
the belt has not slipped out of the groove on the bottom
of the crank pulley.
After installing a new belt, run the engine for approx. 5
minutes and then recheck the tension.

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:
Disconnect the wire from terminal B of the generator
and connect the wire to the negative (−) terminal of
the ammeter.
Connect the test lead from the positive (+) terminal
of the ammeter to terminal B of the generator.
Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
Ground the negative (−) lead of the voltmeter.
(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:
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-
place the voltage regulator.

If the voltage 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 voltage reading of terminal B.
If the voltage reading is higher than the standard
voltage, replace the voltage regulator.
If the voltage reading is less than the standard volt-
age, repair 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 fan control switch
to HI.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than standard amperage, repair
the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.

INSPECTION
1. INSPECT ROTOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
slip rings.
Standard resistance:
2.8 − 3.0 Ω at 20°C (68°F)
If there is no continuity, replace the rotor.
2. INSPECT ROTOR FOR GROUND
Using an ohmmeter, check that there is no continuity between
the slip ring and rotor.
If there is continuity, replace the rotor.
3. INSPECT SLIP RINGS
(a) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(b) Using vernier calipers, measure the slip ring diameters.
Standard diameter:
14.2 − 14.4 mm (0.559 − 0.567 in.)
Minimum diameter:
12.8 mm (0.504 in.)
4. INSPECT STATOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
coil leads.
If there is no continuity, replace the drive end frame assembly.
5. INSPECT STATOR FOR GROUND
