STARTING CIRCUIT CUT-OFF SYSTEM OPERATION
If the engine stop switch is set to “ ” and the main switch is set to “ON” (both switches are closed),
the starter motor can only operate if at least one of the following 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) and the sidestand is up (the
sidestand switch is closed).
The starting circuit cut-off relay prevents the starter motor from operating when neither of these con-
ditions has been met. In this instance, the starting circuit cut-off relay is open so current 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 starter switch.
