STARTING CIRCUIT CUTOFF SYSTEM
OPERATION
If the engine stop sw itch is set to “
” and
the m ain sw itch is set to “ ON” (both
sw itches are closed), the starter m otor can
only operate if at least one of the follow ing
conditions is m et:
• The transm ission is in neutral (the neu-
tral sw itch is closed).
• The clutch lever is pulled to the han-
dlebar (the clutch sw itch is closed) and
the sidestand is up (the sidestand
sw itch is closed).
The starting circuit cutoff relay prevents the
starter m otor from operating w hen neither
of these conditions has been m et. In this
instance, the starting circuit cutoff relay is
open so current cannot reach the starter
m otor. When at least one of the above con-
ditions has been m et the starting circuit cut-
off relay is closed and the engine can be
started by pressing the start sw itch.
