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.

CAUTION:

Check that the battery cables are connected to the
correct terminals.

Disconnect the battery cables when the battery is
given a quick charge.

Do not perform tests with a high voltage insulation
resistance tester.

Never disconnect the battery while the engine is
running.
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
(1) Maintenance±Free Battery:
If under the lower level, replace the battery (or add
distilled water if possible). Check the charging sys-
tem.
(2) Except Maintenance±Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance±Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity: 1.25 ± 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance±Free Battery:
CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery voltage between the negative (±)
and positive (+) terminals of the battery.
Standard voltage: 12.5 ± 12.9 V at 20°C (68°F)
If the voltage is less than 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.
If the terminals are corroded, clean the terminals.
(b) Check the fusible link, H±fuses, M±fuse and fuses for
continuity.
5. INSPECT DRIVE BELTS
(a) Visually check the drive belt for excessive wear, frayed
cords etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of a drive belt are considered acceptable.
If the drive belt has chunks missing from the ribs, it should be
replaced.
(b) Using a belt tension gauge, measure the belt tension.
Belt tension gauge:
DENSO BTG±20 (95506±00020)
Borroughs No. BT±33±73F
Drive belt tension:
New belt175 ± 5 lbf
Used belt115 ± 20 lbf
If the belt tension is not as specified, adjust it.
HINT:

ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.

ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.

After installing a 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 pulley.

After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
6. VISUALLY CHECK GENERATOR WIRING AND
LISTEN 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.
7. CHECK DISCHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Turn off all accessories.
(c) Turn the ignition switch ºONº. Check that the discharge
warning light is lit.
(d) Start the engine. Check that the light goes off.
If the light does not go off as specified, troubleshoot the dis-
charge light circuit.
8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
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:

Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (±) tester probe
of the ammeter.

Connect the positive (+) tester probe of the amme-
ter to terminal B of the generator.

Connect the positive (+) tester probe of the voltme-
ter to terminal B of the generator.

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: 13.5 ± 15.1 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.

If the sides of the lock plate groove are deformed, reas-
sembly of the tank will be impossible.

Therefore, first correct any deformation with pliers or simi-
lar object. Water leakage will result if the bottom of the
lock plate groove is damaged or dented.
