GENERAL DESCRIPTION
STARTING CIRCUIT
The cranking system consists of a battery, starter, starter switch, starter relay, etc. and these main compo-
nents are connected as shown in Figure. For details of the starting circuit.
STARTER
The starting system employs a magnetic type
reduction starter in which the motor shaft is also
used as a pinion shaft. When the starter switch is
turned on, the contacts of magnetic switch are
closed, and the armature rotates. At the same time,
the plunger is attracted, and the pinion is pushed
forward by the shift lever to mesh with ring gear.
Then, the ring gear runs to start the engine. When
the engine starts and the starter switch is turned off,

the plunger returns, the pinion is disengaged from ring
gear, and the armature stops rotation. When the engine
speed is higher than the pinion, the pinion idles, so that
the armature is not driven.
