Free Running Test

1. Place the starter motor in a vise equipped with soft jaws and connect a fully-charged 12 volts battery to the starter motor as follows:
2. Connect a test ammeter (100 amperes scale) and carbon pile rheostat in series between the positive battery terminal and starter motor terminal.
3. Connect a voltmeter (15 volts 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.
