Starter Motor
The starter motor is small in size light weight and high-
output type.
Rotation of the motor are reduced by the reduction
gear, and high torque is transmitted to the pinion gear.
Operation
1. When the ignition key (IG-SW) is turned to the “ST”
position, current flows from the S terminal of the magnetic
switch to the pull-in coil and the holding coil.
Current from the pull-in coil passes through the M terminal,
flows to the starter’s brush, commutator, and armature,
and then the armature begins to gently turn.
