FREE RUNNING TEST
1. Place starter motor in a vise equipped with soft jaws
and connect a fully-charged 12-volt battery to starter motor
as follows:
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-volt 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.
7. Confirm that the maximum amperage is within the
specifications and that the starter motor turns smoothly
and freely.
Current: max. 90 Amps
MAGNETIC SWITCH RETURN TEST
1. Disconnect field coil wire from M-terminal of magnetic
switch.
2. Connect a 12V battery between M-terminal and body.
Caution
This test must be performed quickly (in less than
10 seconds) to prevent coil from burning.
3. Pull pinion out and release. If pinion quickly returns to
its original position, everything is in order. If it doesn’t,
replace magnetic switch.
Caution
Be careful not to get your fingers caught when pulling
out the pinion.
