IT RUNS
IT FAILS TO RUN The starter is defective. Repair or replace.
IT FAILS TO RUNThe starter relay is defective. Replace.
3. Starter
•Connect the positive terminal of the bat-
tery (1) and the starter cable (2) using a
connection cable (3) *.
•Check the functioning of the starter.
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 that no flammable
gas or fluid is in the vicinity.

4. Starter relay.
•Disconnect the starter relay connector.
•Connect the battery and frame to the
starter relay connector, using a connec-
tion cable (1) as shown.
