STARTING CIRCUIT CUTOFF SYSTEM
OPERATION
If the engine stop switch is set to "
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 neu-
tral switch is closed).
• The clutch lever is pulled to the handle-
bar (the clutch switch is closed) and the
sidestand is up (the sidestand switch is
closed).
The starting circuit cutoff relay prevents the
starter motor from operating when neither
of these conditions has been met. In this
instance, the starting circuit cutoff relay is
open so current cannot reach the starter
motor. When at least one of the above con-
ditions has been met the starting circuit cut-
off relay is closed and the engine can be
started by pressing the start switch.
