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).
