(c) Measure the battery voltage between the negative (±)
and positive (+) terminals of the battery.
Standard voltage:
12.5 to 12.9 V at 20°C (68°F)
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
HINT:
Since the belt tensioner is used, checking the belt tension is not
necessary.
(a) Visually check the drive belt for excessive wear, frayed
cords etc.
If necessary, replace the drive belt.
HINT:

Cracks on the rib side of a drive belt are considered ac-
ceptable. If the drive belt has chunks missing from the
ribs, it should be replaced.

The drive belt tension can be released by turning the belt
tensioner counterclockwise. The pulley bolt for the belt
tensioner has a left±hand thread.
(b) Check the belt tensioner operation.

Check that the belt tensioner moves downward
when the drive belt is pressed down at the points in-
dicated in the illustration with approx. 98 N (10 kgf,
22.0 lbf) of force.

Check the alignment of the belt tensioner pulley to
make sure the drive belt does not slipped off the
pulley.
If necessary, replace the belt tensioner.

Check that the arrow mark on the belt tensioner falls
within area A of the scale.
If it is outside area A, replace the drive belt.
HINT:

When a new belt is installed, it should lie within area B. If
not, the drive belt is not correct.

After installing a belt, check that it fits properly in the
ribbed grooves.

Check by hand to confirm that the belt does not slipped
out of the groove on the bottom of the pulley.
6. REMOVE ENGINE UNDER COVER NO.1
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 CHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Switch off all accessories.
(c) Turn the ignition switch ON, and check that the charge
warning light comes on.
(d) Start the engine, and check that the light goes off.
If the light does not go off as specified, troubleshoot the charge
light circuit.
9. 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: 13.2 to 14.0 V
