STARTING SYSTEM-General Information 8-91
STARTING SYSTEM
GENERAL INFORMATION
NOBFAAJ
The electrical circuit of the starter system consists of battery, starter motor, solenoid switch, ignition switch,
inhibitor switch, connecting wire and battery cable.
In the starter system and electrical circuit, electricity flows to activate the coils of the starter motor solenoid when
the ignition switch is turned to the start position. In so doing, the solenoid plunger and clutch shift lever move, the
clutch pinion engages with the ring gear and then the solenoid contacts shut and the starter motor cranks.
As soon as the engine begins to run and, in order to prevent damage due to over-revolution by the armature starter,
the running clutch pinion gear over-rides, Thus in order not to cause damage to the starter motor once the engine
is running, the ignition switch must be immediately turned back to the ON position.
The starter motor is the reduction-drive type, and is compact and lightweight.

The distributor is composed of signal generator (signal rotor and igniter internalized pickup), linear current control
unit (igniter) advance control unit (governor and vacuum controller) and distribution unit (rotor plus distributor cap).

IGNITER OPERATION
(1) When the signal rotor revolves a projection inside the signal rotor alternately moves away from and faces
towards the core detector inside the igniter.
(2) When the projection is separated from the core, an oscillating electrical circuit begins to oscillate, and when it
faces, magnetic flux issuing from the core moves across the inside of the signal rotor, so when loss increases,
oscillation ceases.
(3) This oscillation introduces power to the oscillation detector circuit, and after output is amplified it drives the
power transistor. During oscillation (when the projection and core are apart) electricity flowing through the
ignition coil and when oscillation stops (when the projection and core are facing) the electric current is inter-
rupted.
(4) The electrical detection circuit, in preventing excessive electrical flow to the power transistor, protects the
transistor.
