STARTING SYSTEM
GENERAL INFORMATION
If the ignition switch is turned to the ªSTARTº
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 ªONº
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.
