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

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.

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

shown in the drawing and soldering the lead.

STARTING SYSTEM

GENERAL INFORMATION

M1162000100310

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.

STARTER MOTOR ASSEMBLY INSPECTION

M1162001100250

PINION GAP ADJUSTMENT

1. Disconnect the field coil wire from the M-terminal 

of the magnetic switch.

2. Connect a 12-volt battery between the S-terminal 

and M-terminal.

CAUTION

This test must be performed quickly (in less than 
10 seconds) to prevent the coil from burning.
3. Set the switch to "ON", and the pinion will move 

out.

4. Check the pinion-to-stopper clearance (pinion 

gap) with a feeler gauge.

Standard value: 0.5 

 2.0 mm

5. If the pinion gap is out of specification, adjust by 

adding or removing gasket(s) between the 
magnetic switch and front bracket.

MAGNETIC SWITCH PULL-IN TEST

1. Disconnect the field coil wire from the M-terminal 

of the magnetic switch.

CAUTION

This test must be performed quickly (in less than 
10 seconds) to prevent the coil from burning.
2. Connect a 12-volt battery between the S-terminal 

and M-terminal.

3. If the pinion moves out, the pull-in coil is good. If it 

doesn't, replace the magnetic switch.

MAGNETIC SWITCH HOLD-IN TEST

1. Disconnect the field coil wire from the M-terminal 

of the magnetic switch.

CAUTION

This test must be performed quickly (in less than 
10 seconds) to prevent the coil from burning.
2. Connect a 12-volt battery between the S-terminal 

and body.

3. Manually pull out the pinion as far as the pinion 

stopper position.

4. If the pinion remains out, everything is in order. If 

the pinion moves in, the hold-in circuit is open. 
Replace the magnetic switch.
