2. Check the 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 the 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
M1162000100149
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 switched to the "ST" position while the
selector 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 dose not operate at all.
• 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 chart.
STEP 1.
Q: Is the battery in good condition? (Refer to GROUP 54A,
Battery
− Battery check
YES : Go to Step 2.
NO : Charge or replace the battery.
STEP 2.
• Disconnect the starter motor S (solenoid) terminal connec-
tor.
• Using a jumper wire, apply battery voltage to the starter
motor S (solenoid) terminal.
• Check the engine condition.
OK: Turns normally
Q: Does the starter motor operate normally?
YES :
• Check the ignition switch. (Refer to GROUP 54,
• Check the starter relay
• Check the transmission range switch.(Refer to
GROUP 23A, Automatic Transaxle On-vehicle
Service
• 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
