ELECTRIC STARTING SYSTEM
(TT-R90E)
STARTING CIRCUIT CUT-OFF SYSTEM
OPERATION
If the main switch is set to “ON”, the starter
motor can only operate if the following condi-
tion is met:
• The transmission is in neutral (the neutral
switch is closed).
The starting circuit cut-off relay prevents the
starter motor from operating when this condi-
tion has not been met. In this instance, the
starting circuit cut-off relay is open so current
cannot reach the starter motor. When the
above condition has been met the starting cir-
cuit cut-off relay is closed and the engine can
be started by pressing the start switch.
