STARTING CIRCUIT CUT-OFF SYSTEM OPERATION
If the main switch is set to “ON” (switch circuit is closed), the starter motor can only operate if the fol-
lowing conditions are met:
• The brake lever is pulled to the handlebar (the brake 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 condi-
tions 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 start switch “”.
