Starter Ground Circuit Test

NOTE: Make all voltmeter connections at component terminal rather than at cable or wire end.
  1. Disconnect and ground coil wire from distributor cap to prevent engine from starting. Connect remote starter switch between starter solenoid terminal "S" and battery positive terminal.
  2. Connect positive DVOM lead to starter motor housing. Ensure connection point is clean and free of rust and grease. Connect negative voltmeter lead to negative battery terminal.
  3. Engage remote starter switch. Observe and record voltmeter indication while cranking engine. Voltmeter should indicate 0.2 volt or less. If voltage drop is greater than 0.2 volt, clean negative battery cable connections at battery and body connections. Retest to verify problem has been corrected.
  4. If voltage drop is still excessive, replace negative battery cable(s) as necessary. If battery cables test okay, but starter still cranks slowly or not at all, remove and repair starter motor.
