STARTING CIRCUIT OPERATION
The starting circuit on this model consists of the
starter motor, starter relay, and the starting circuit
cut-off relay. If the engine stop switch is on “RUN”
and the main switch is on “ON” (both switches are
closed), the starter motor can operate only if:
The starting circuit cut-off relay prevents the
starter from operating when neither of these con-
ditions have been met. In this instance, the start-
ing circuit cut-off relay is open so current cannot
reach the starter motor.
When at least one of the above conditions have
been met however, the starting circuit cut-off relay
is closed, and the engine can be started by press-
ing the starter switch.

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.
