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 (0.08 inch) 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

M1162000100859

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

For models equipped with A/T, when the ignition 
switch is turned to the "ST" position while the selec-
tor lever is at the "P" or "N" position, the contact 
(magnetic switch) of the starter is switched ON and 
the starter motor is activated.

TROUBLESHOOTING HINTS

The starter motor does not operate at all.

WARNING

Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER 
HANDLING.

• Check the starter (coil).

• Check for poor contact at the battery terminals and 

starter.

• Check the transmission range switch.

The starter motor doesn't stop

• Check the starter (magnetic switch).

TROUBLESHOOTING GUIDE

The starting system troubleshooting guide is shown in the fol-
lowing steps.

WARNING

STEP 2.

• Disconnect the starter motor S (solenoid) terminal connec-

tor.

• Using a jumper wire, apply battery positive voltage to the 

starter motor S (solenoid) terminal.

• Check the engine condition.

OK: Turns normally

Q: Dose the starter motor operate normally?

YES : 

• Check the ignition switch (Refer to GROUP 54A, 

Chassis Electrical 

− Ignition Switch − Ignition 

Switch 

− Inspection 

P.54A-26

.)

• Check the transmission range switch. (Refer to

.) <3.0L>

• Check the line between the battery and starter 

motor S (solenoid) terminal.

NO :  Go to Step 3.

STEP 3.

• Check the cable between starter B (battery) terminal and 

battery positive terminal for connection and continuity.

Q: Is the starter cable in good condition?

YES : Go to Step 4.
NO :  Repair or replace the cable.

STEP 4.

• Check the connection and the continuity of the cable 

between the starter motor body and the negative battery 
terminal.

Q: Is the ground line in good condition?

YES : Go to Step 5.
NO :  Repair or replace the cable.

STEP 5.
Q: Is the starter motor in good condition? (Refer to Starting 

System 

− Starter Motor Assembly − Inspection
