BA 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.

RECTIFIERS 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.

INSPECTION
PINION GAP ADJUSTMENT
1. Disconnect field coil wire from M-terminal of magnetic
switch.
2. Connect a 12 V battery between S-terminal and
M-terminal.
3. Set switch to “ON” position, and pinion will move out.
Caution
This test must be performed quickly (in less than
10 seconds) to prevent coil from burning.
4. Check pinion to stopper clearance (pinion gap) with a
thickness gauge.
