Insulated Circuit Test

  1. Make sure battery is at full charge. Adjust voltmeter switch to 4 volt position. Disconnect coil wire at distributor cap.
  2. Connect voltmeter positive lead to positive battery terminal. Connect voltmeter negative lead to solenoid connector that connects to starter field coils.
    NOTE: It will be necessary to peel back rubber boot to gain access to connector. Also, the voltmeter will read off scale until engine is cranked over.
  3. Crank engine over with a remote starter switch. Check voltmeter reading. A voltage drop of 0.3 volt or less indicates voltage drop is normal.
  4. If voltmeter reads more than.3 volt, high resistance is indicated in starter insulated circuit.
  5. Disconnect voltmeter from solenoid connector. Reconnect to the following points and repeat test at each connection.
    • Solenoid starter terminal.
    • Solenoid battery terminal.
    • Starter relay.
    • Battery cable connection.
  6. A small change will occur each time a portion of the circuit is removed from test. A definite change in voltmeter indicates last part eliminated in test is at fault.
