Insulated Circuit Test


1. Turn voltmeter selector knob to 4 volt position.
2. Disconnect ignition coil secondary cable.
3. Connect voltmeter positive lead to battery positive post and voltmeter negative lead to solenoid connector that connects to starter field coils. It may be necessary to peel back rubber boot on solenoid to reach solenoid connection. Voltmeter will read off scale to right until starter is actuated.
4. Connect remote control starter switch to battery solenoid terminal of starter relay.
5. Crank engine with remote control starter switch while observing voltmeter reading. If voltmeter reading exceeds .3 volt, there is high resistance in starter insulated circuit, proceed as follows:
a. Remove voltmeter lead from solenoid connector and connect to following points, repeating test at each connection. Starter terminal of solenoid, battery terminal of solenoid, battery cable terminal at solenoid, starter relay and cable clamp at battery.
b. A small change will occur each time a normal portion of circuit is removed from test. A definite change in voltmeter reading indicates that last part eliminated in test is at fault.
