>>B<< ROTOR INSTALLATION

AK202779

Wire

AB

Remove the brush holding wire after the rotor has
been installed.

ROTOR

AK202735

1. Measure the resistance between the two slip rings

of the rotor coil to check the continuity between
them.
Replace the rotor if the resistance is not within the
standard value range.

Standard value: 2

− 4 Ω

2. Check the continuity between the slip rings and

core.

AK202736

3. If continuity is present, replace the rotor.

STATOR

AK202716

1. Check the continuity between coil leads.

If there is no continuity, replace the stator.

AK202717

2. Check the continuity between coil and core.

If there is no continuity, replace the stator.

RECTIFIER ASSEMBLY

AK202803

1. Check the condition of the (+) heat sink by

checking continuity between the (+) heat sink and
each of the stator coil lead connecting terminals.
If continuity is present for both terminals, the
diode is shorted. Replace the rectifier assembly.

2. Check the condition of the (

−) heat sink by

checking continuity between the (

−) heat sink and

each of the stator coil lead connecting terminals.
If continuity is present in both directions, the diode
is shorted. Replace the rectifier assembly.

AK202804

3. Check the condition of the diode trio by testing

continuity of each of the three diodes using a
circuit tester connected to both sides of the diode.
Connect in a polarity and then reverse the polarity
for each test.
If continuity exists or no continuity exists for both
polarities, the diode is defective. Replace the
rectifier assembly if any of the diodes is defective.

BRUSH

AK202808

Protrusion
length

AB

1. Measure the length of the protrusion of the brush.

Replace the brush if the protrusion length is
shorter than the limit.

Limit: 2 mm minimum

2. Unsolder the lead of the brush. The brush will

come out, becoming ready for removal.

AK202834

Solder

AB

3. Install a new brush by pushing it into the holder as

shown in the drawing and soldering the lead.

STARTING SYSTEM

GENERAL INFORMATION

M1162000100592

If the ignition switch is turned to the "START" posi-
tion, current flows in the pull-in and holding coils pro-
vided inside magnetic switch, attracting the plunger,
When the plunger is attracted, the lever connected to
the plunger is actuated to engage the starter clutch.
On the other hand, attracting the plunger will turn on
the magnetic switch, allowing the "B" terminal and
"M" terminal to conduct. Thus, current flows to
engage the starter motor.

When the ignition switch is returned to the "ON" posi-
tion after starting the engine, the starter clutch is dis-
engaged from the ring gear.
An overrunning clutch is provided between the pinion
and the armature shaft, to prevent damage to the
starter.
