• When the solenoid switch is closed
The current from the battery flows through the solenoid
switch (2) to the starting motor.
The pinion (7), which is pushed against the ring gear (8)
and rotated along the spline (5), meshes with the ring gear to
crank the engine.
The engine starts and increases its speed.
While the pinion spins faster than the armature, the over ­
running clutch (6) allows the pinion to spin independently
from the armature.
The pull-in coil (3) is short-circuited through the solenoid
switch (2) and the key switch (1).

• When the key switch is released
The current from the battery flows to the holding coil
(1) through the pull-in coil (2) to diminish the magnetism
between them.
The plunger (3) is pushed by the spring to pull in the pinion.

• When key switch is turned to "START" position
The contacts of key switch (1) close and the holding coil (3)
is connected to the battery to pull the plunger (5).
The pull-in coil (4) and the starting motor are also connected
to the battery.
The pinion (8) is pushed against the ring gear (9) with the
overrunning clutch (7) by the shift lever (6) and the magnetic
switch (2) is closed.
