Hold-In Windings Test

If solenoid switch is not removed from starter motor assembly, disconnect field lead from terminal "M" on solenoid switch. Connect an ammeter in series with 12-volt battery and terminal "S" on starter solenoid. See Figure . Connect a voltmeter between solenoid terminal "S" and ground. Connect a carbon pile rheostat across battery. Adjust voltage to 10 volts and check amperage reading. If amperage reading is not between 10-20 amps (13-19 amps, 4.9L), replace solenoid.
