b. Turn the main switch to "ON".
c. Elevate the front wheel and slowly rotate it.
d. Measure the voltage with each full rotation
of the front wheel, the voltage reading
should cycle from Lo (0.5–0.9 V) to Hi (1.1–
1.7 V) to Lo to Hi.

CHECKING THE STARTOR MOTOR OPERA-
TION
1. Check:
• Starter motor operation
Does not operate → Perform the electric
starting system troubleshooting, starting
with step 5.
Refer to "TROUBLESHOOTING" on page
9-1.

a. Connect the positive battery terminal "1"
and starter motor lead "2" with a jumper
lead "3".
EWA13810
WARNING
• A wire that is used as a jumper lead must
have at least the same capacity of the bat-
tery, otherwise the jumper lead may burn.
• This check is likely to produce sparks,
therefore, make sure no flammable gas or
fluid is in the vicinity.
b. Check the starter motor operation.

2. Check:
• Stator coil resistance
ELECTRICAL COMPONENTS
Out of specification → Replace the stator
coil.

CHECKING THE STATOR COIL
1. Disconnect:
• Stator coil coupler
(from the wire harness)
2. Check:
• Stator coil resistance
Out of specification → Replace the stator
coil.
Stator coil resistance
0.22–0.34 Ω at 20°C (68°F)
