CHECKING THE STARTER MOTOR
OPERATION
1. Check:
• Starter motor operation
Does not operate → Perform the electric

WARNING
• A wire that is used as a jumper lead must
have at least the same capacity of the bat-
tery lead, 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.

1. Disconnect:
• Stator coil coupler
(from the rectifier/regulator)
2. Check:
• Stator coil resistance
Out of specification → Replace the stator coil.
