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 90 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.

DISASSEMBLY SERVICE POINTS

.

<<A>> SNAP RING AND STOP RING REMOVAL
1. Press a long socket wrench of appropriate size to the stop 

ring. Then tap the socket wrench to remove the stop ring to 
the pinion gear side.

2. After removing the snap ring (by using snap-ring pliers), 

remove the stop ring and the overrunning clutch.

STARTER MOTOR PART CLEANING

1. Do not immerse parts in cleaning solvent. Immersing the 

yoke and field coil assembly and/or armature will damage 
insulation. Wipe these parts with a shop towel only.

2. Do not immerse the drive unit in cleaning solvent. 

Overrunning clutch is pre-lubricated at the factory and 
solvent will wash lubrication from the clutch.

3. The drive unit may be cleaned with a brush moistened with 

cleaning solvent and wiped dry with a shop towel.
