DISASSEMBLY SERVICE POINTS
<<A>>FRONT BRACKET ASSEMBLY
REMOVAL
AK202718
CAUTION
Do not insert the screwdriver blades too deep.
Doing so could damage the stator coil.
Insert the blades of screwdrivers between the front
bracket assembly and stator core, and pry and sepa-
rate them with the screwdrivers.
<<B>>ALTERNATOR PULLEY REMOVAL
AK202714
CAUTION
Perform operation carefully not to damage the
rotor.
Clamp the rotor in a vise with the pulley facing up to
remove the pulley.

CAUTION
• Use a 180 − 250 W soldering iron, and finish
unsoldering within four seconds. Diodes will
be damaged by heat if unsoldering time is too
long.
• Avoid applying undue force to the diode
leads.
1. Unsolder the stator leads from the main diode of
the rectifier assembly when the stator is removed.
2. When removing the rectifier assembly from the
regulator assembly, undo the soldered points on
the rectifier assembly.

After installing the regulator assembly, insert a piece
of wire through the hole in the rear bracket while
pressing the brush to keep the brush against move-
ment.

INSPECTION

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: 3
− 5 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 ASSEBMLY
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
M1162000100202
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.
