5. If pinion gap is out of specification, adjust by adding or
removing gaskets between magnetic switch and front
bracket.
MAGNETIC SWITCH PULL-IN TEST
1. Disconnect field coil wire from M-terminal of magnetic
switch.
2. Connect a 12 V battery between S-terminal and
Battery
M-terminal.
Caution
This test must be performed quickly (in less than
10 seconds) to prevent coil from burning.
3. If pinion moves out, then pull-in coil is good. If it doesn't,
replace magnetic switch.
MAGNETIC SWITCH HOLD-IN TEST
1. Disconnect field coil wire from M-terminal of magnetic
switch.
2. Connect a 12 V battery between S-terminal and body.
Caution
Battery
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.
3. Manually pull out the pinion as far as the pinion stopper
position.
4. If pinion remains out, everything is in order. If pinion moves
in, hold-in circuit is open. Replace magnetic switch.
FREE RUNNING TEST
1. Place starter motor in a vise equipped with soft jaws
and connect a fully-charged 12 V battery to starter motor
as follows:
A
2. Connect a test ammeter (100-ampere scale) and carbon

pile rheostat in series with battery positive post and starter
motor terminal.

3. Connect a voltmeter (15 V scale) across starter motor.
4. Rotate carbon pile to full-resistance position.
5. Connect battery cable from battery negative post to starter
motor body.
6. Adjust the rheostat until the battery voltage shown by
the voltmeter is 11 V Reduction.
7. Confirm that the maximum amperage is within the
specifications and that the starter motor turns smoothly
and freely.
