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

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 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.
