STARTING SYSTEM
GENERAL INFORMATION
M1161000101309
If the ignition switch is turned to the "START" posi-
tion, current flows in the coil provided inside mag-
netic 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" posi-
tion after starting the engine, the starter clutch is dis-
engaged from the ring gear.
An overrunning clutch is provided between the pinion
and the armature shaft, to prevent damage to the
starter.

OPERATION
For models equipped with TC-SST, when the ignition
switch is turned to the "ST" position while the selec-
tor lever is at the "P" or "N" position, the contact
(magnetic switch) of the starter is switched ON and
the starter motor is activated.
