3. Inspect the commutator copper bars for discolor-
ation. If a pair of bars is discolored, armature coils
are grounded. Replace the starter.
4. Measure the diameter of the commutator with a
vernier caliper. Replace the starter if the commuta-
tor diameter is less than the service limit specified in
Table 1
.
5. Use an ohmmeter to perform the following:
a. Check for continuity between the commuta-
tor bars (
Figure 44
). There should be conti-
nuity (zero or low resistance) between pairs
of bars.
b. Check for continuity between the commuta-
tor bars and the armature shaft (
Figure 45
).
There should be
no
continuity (infinite resis-
tance).
c. If the unit fails any of these tests, replace the
starter.
6. Inspect the bushing (
Figure 46
) in the rear end
cap for wear or damage. If it is damaged, replace the
starter.
7. Inspect the bearing and oil seal in the front end
cover (A,
Figure 41
). If either is worn or damaged,
replace the starter.
8. Inspect the teeth of the planetary gears (B,
Fig-
ure 41
) and ring gear (C) for chipped, cracked or
broken teeth.
9. Clean all dirt and contaminants from the mount-
ing lugs of the rear end cover. The lugs ground the
starter so there must be good contact between the
starter lugs and the crankcase.
STARTING CIRCUIT
CUTOFF RELAY
The starting circuit cutoff relay (SCCR) inter-
rupts the flow of current to the starter relay unless
the transmission is in neutral or unless the clutch le-
ver is pulled in and the sidestand is up.
SCCR Removal/Installation
1. Securely support the motorcycle on a level sur-
face.
2. Remove the fuel tank, air filter housing and
surge tank as described in Chapter Eight.
3. Remove the frame neck covers (Chapter Four-
teen).
