ELECELECTRICAL STARTING SYSTEM

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 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.
