REGULATOR ASSEMBLY INSTALLATION
After installing the regulator assembly, insert a wire into the
hole provided on the rear bracket while pressing in the brush
to fix the brush.
NOTE
The brush is fixed when a wire is inserted, making rotor
installation easier.

ROTOR INSTALLATION
After installing the rotor, remove the wire used to fix the brush.
INSPECTION
ROTOR CHECK
1.
Check the continuity between the rotor coil slip rings, and
replace the rotor if the resistance value is not at the
standard value.
Standard value: 3 – 5
Ω
2.
Check the continuity between the slip ring and core, and
if there is continuity, replace the rotor.

STATOR CHECK
1.
Check the continuity between the coil leads, and if there
is continuity, replace the stator.
2.
Check the continuity between the coil and core, and if
there is continuity, replace the stator.
RECTIFIER CHECK
1.
Inspect the (+) heat sink by checking the continuity between
the (+) heat sink and stator coil lead wire connection
terminal using a tester probe.
If there is a continuity at both, the diode is short circuited,
so replace the rectifier.
2.
Inspect the (–) heat sink by checking the continuity between
the (–) heat sink and stator coil lead wire connection
terminal using a tester probe.
If there is a continuity at both, the diode is short circuited,
so replace the rectifier.
3.
Check the diode trio by connecting an ohmmeter to both
ends of each diode and check the continuity of the three
diodes.
If there is a continuity at both ends, or if there is no
continuity, the diode is damaged so replace the rectifier.

BRUSH CHECK
1.
Measure the length of the brush protrusion shown in the
illustration, and replace the brush if the measured value
is below the limit value.
Limit: 2 mm or less
2.
The brush can be removed if the solder of the brush lead
wire is removed.
3.
When installing a new brush, insert the brush into the
holder as shown in the illustration, and then solder the
lead wires.

STARTING SYSTEM
GENERAL INFORMATION
If the ignition switch is turned to the “START”
position, current flows in the pull-in and holding coils
provided 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”
position after starting the engine, the starter clutch
is disengaged from the ring gear.
An overrunning clutch is provided between the pinion
and the armature shaft, to prevent damage to the
starter.
