STARTING AND CHARGING SYSTEM (Y22SE 2.2L)

Starting System

General Description

Cranking Circuit

The cranking system consists of a battery, starter, starter
switch, starter relay, etc. These main components are
connected.

Starter

The cranking 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 the 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 the 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.

Inspection and Repair

Repair or replace necessary parts if extreme wear or
damage is found during inspection.

Armature

Check for continuity between commutator and segment.
Replace commutator if there is no continuity (i.e.,
disconnected).

065RS015

Check for continuity between commutator and shaft.
Also, check for continuity between commutator and
armature core,armature core and shaft. Replace
commutator if there is continuity (i.e., internally
grounded).

065RS016

Brush

Measure the length of brush.
Replace with a new one, if it is below the limit.

Brush Holder

Check for continuity between brush holder (+) (4) and
base (–). Replace, if there is continuity (i.e., insulation is
broken).

065RW015

Magnetic Switch

Check for continuity of shunt coil between terminals S and
M.
Replace, if there is no continuity (i.e., coil is
disconnected).
