STARTING SYSTEM
GENERAL INFORMATION
If the ignition switch is turned to the ”START”
position, current flows in the pull-in and holding
coils provided inside magnetic switch, attracting
the plunger. When the plunger is attracted, the
lever connected to the plunger is actuated to
engage the starter clutch.
On the other hand, attracting the plunger will turn
on the magnetic switch, allowing the B terminal
and M terminal to conduct. Thus, current flows to
engage the starter motor.
When the ignition switch is returned to the “ON”
position after starting the engine, the starter clutch
is disengaged from the ring gear.
An overrunning clutch is provided between the
pinion and the armature shaft, to prevent damage
to the starter.
