ASSEMBLY SERVICE POINTS
.
>>A<< REGULATOR ASSEMBLY INSTALLATION
After installing the regulator assembly, insert a wire through the
hole provided on the rear bracket while pressing down on the
brush, and secure the brush.
NOTE: By inserting a wire, the brush will be secured in place,
and the installation of the rotor will be easier.
.
>>B<< ROTOR ASSEMBLY INSTALLATION
After installing the rotor, remove the wire used to secure the
brush.

ROTOR CHECK
1. Check for continuity between the slip rings of the field coil. If
the resistance value is not within the standard value, replace
the rotor.
Standard value: approximately 2
− 5 Ω

2. Check for continuity between the slip ring and the core. If
there is continuity, replace the rotor.
.
STATOR CHECK
1. Check for continuity between the coil lead. If there is no
continuity, replace the stator.
2. Check for continuity between the coil and the core. If there is
continuity, replace the stator.
.
RECTIFIER CHECK
1. Check for continuity between the positive rectifier and the
stator coil lead connection terminal with a tester. If there is
continuity between the terminals, the diode is shorted, so
replace the rectifier.

2. Check for continuity between the negative rectifier and the
stator coil lead connection terminal with a tester. If there is
continuity between the terminals, the diode is grounded, so
replace the rectifier.
3. Check for continuity of the three diodes by connecting an
ohmmeter to both ends of each diode. If there is continuity
between the directions, or if there is no continuity, the diode
is damaged, so replace the rectifier.
.
BRUSH CHECK
1. Replace the brush if the brush protrusion length shown in
the illustration is below the minimum limit value.
Minimum limit: 2 mm (0.08 inch)
2. The brush can be removed by unsoldering the brush lead
wire.
3. When installing a new brush, push the brush in to the brush
holder, and solder the lead wire.

STARTING SYSTEM
GENERAL DESCRIPTION
M1162000100257
If the ignition switch is turned to the "START" posi-
tion, current flows in the coil provided inside mag-
netic 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.
OPERATION
When the ignition switch is switched to the "ST" posi-
tion while the selector lever is at the "P" or "N" range,
the contact (magnetic switch) of the starter is
switched ON and the starter motor is activated.
