Starter W/Integral Positive Engagement Drive

Disconnect vacuum line to Thermactor bypass valve before performing any cranking tests. After tests, run engine 3 minutes before connecting vacuum line.

Starter Cranking Circuit Test

Fig. 4 Starter Cranking Circuit Test Connections:

1. Make test connections as shown in Fig. 4.
2. Disconnect ignition coil and crank engine.
3. Connect remote control starter switch from battery terminal of starter relay to S terminal of relay.
4. Maximum allowable voltage drop should be as follows:
a. .5 volt with voltmeter negative lead connected to starter terminal and positive lead connected to battery positive terminal.
b. .1 volt with voltmeter negative lead connected to starter relay (battery side) and positive lead connected to positive terminal of battery.
c. .3 volt with voltmeter negative lead connected to starter relay (starter side) and positive lead connected to positive terminal of battery.
d. .3 volt with voltmeter negative lead connected to negative terminal of battery and positive lead connected to engine ground.

Starter Load Test

Fig. 5 Starter Load Test Connection. Positive Engagement Starter:

1. Connect test equipment as shown in Fig. 5.
2. Ensure that no current is flowing through ammeter and heavy duty carbon pile rheostat portion of circuit.
3. Crank engine with ignition off and determine exact reading on voltmeter. This test is accomplished by disconnecting push-on connector S at starter relay and by connecting a remote control starter switch from positive battery terminal to S terminal of starter relay.
4. Stop cranking engine and reduce resistance of carbon pile until voltmeter indicates same reading as that obtained while starter cranked engine. Ammeter should read 150-250 amps.
