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 wire 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
YES : Excessive rotational resistance of the engine.
NO : Replace the starter motor.

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 sec-
onds) 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 (0.02 − 0.07 inch)
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 sec-
onds) 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 sec-
onds) 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 operating properly. If
the pinion moves in, the hold-in circuit is open. Replace the
magnetic switch.
.
FREE RUNNING TEST
1. Place the starter motor in a vise equipped with soft jaws and
connect a fully-charged 12-volt battery to the starter motor
as follows:
2. Connect a test ammeter (100-ampere scale) and carbon pile
rheostat in series between the positive battery terminal and
starter motor terminal.
3. Connect a voltmeter (15-volt scale) across the starter motor.
4. Rotate the rheostat to full-resistance position.
5. Connect the battery cable from the negative battery terminal
to the starter motor body.
6. Adjust the rheostat until the battery positive voltage shown
on the voltmeter is 11 V.
7. Confirm that the maximum amperage is within the
specifications and that the starter motor turns smoothly and
freely.
Current: maximum 95 Amps
.
MAGNETIC SWITCH RETURN 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 sec-
onds) to prevent the coil from burning.
2. Connect a 12-volt battery between the M-terminal and body.
WARNING
Be careful not to get your fingers caught when pulling
out the pinion.
3. Pull the pinion out and release. If the pinion quickly returns
to its original position, everything is operating properly. If it
doesn't, replace the magnetic switch.
