ELECTRIC STARTING SYSTEM

STARTING CIRCUIT CUT-OFF SYSTEM
OPERATION
If the main switch is set to "ON", the starter mo-
tor can only operate if at least one of the follow-
ing conditions is met:
• The transmission is in neutral (the neutral
switch is closed).
• The clutch lever is pulled to the handlebar (the
clutch switch is closed).
The starting circuit cut-off relay prevents the
starter motor from operating when neither of
these conditions has been met. In this instance,
the starting circuit cut-off relay is open so cur-
rent cannot reach the starter motor. When at
least one of the above conditions has been met
the starting circuit cut-off relay is closed and the
engine can be started by pressing the start
switch.
