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 fol-
lows :
2. Connect a test ammeter (loo-ampere scale) and carbon pile

terminal.
3. Connect a voltmeter (16volt 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 rheostat until battery voltage shown on the voltme-
ter reads 1 IV.
7. Confirm that the maximum amperage is within the stand-
ard value and that the starter motor turns smoothly and
freely.
Standard value : Current
Speed
Max. 90A
Min. 3,000 rpm
RETURN TEST OF MAGNETIC SWITCH
1. Disconnect field coil wire from “M” terminal of magnetic
