GENERAL DESCRIPTION
STARTING CIRCUIT
The cranking system consists of a battery, starter,
starter switch, starter relay, etc. and these main components 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.
