Stator Solenoid Test
1. Disconnect the field coil wire from the M-terminal of
solenoid switch.
2. Connect a 12V battery between S-terminal and the
starter body.
3. Connect the field coil wire to the M-terminal.
CAUTION
This test must be performed quickly (in less than
10 seconds) to prevent the coil from burning .
4. If the pinion moves out, the pull-in coil of solenoid is
working properly.
If the pinion does not move, replace the solenoid.
5. Disconnect the field coil wire from the M-terminal.
6. If the pinion has moved out, the hold-in coil of the
solenoid is working properly.
If the pinion moves in, replace the solenoid.
Free Running Test
1. Place the 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 rheostats shown is the illustration.
3. Connect a voltmeter (15-volt scale) across starter
motor.
4. Rotate carbon pile to the off position.
5. Connect the battery cable from battery's negative
post to the starter motor body.
6. Adjust until battery voltage shown on the voltmeter
reads 11volts.
7. Confirm that the maximum amperage is within the
specifications and that the starter motor turns
smoothly and freely.
