12. INSPECT BRUSH HOLDER INSULATION
Using an ohmmeter, check that there is no continuity between
the positive (+) and negative (±) brush holders.
If there is continuity, repair or replace the brush holder.
13. INSPECT GEAR TEETH
Check the gear teeth on the pinion gear, idle gear and the clutch
assembly for wear or damage.
If any damage is found, replace the gear or clutch assembly,
and also check the drive plate ring gear for wear or damage.

(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.
