Starter Circuit Voltage Drop Test

NOTE: If starter cranks slowly and battery is okay, perform following test.
  1. Check engine ground strap and negative battery cable connections and repair as necessary. Prevent engine from starting by disabling ignition system. Ensure transmission is in Park or Neutral. Connect remote control starter switch between starter solenoid "S" terminal and positive battery terminal. See Figure.
  2. Connect voltmeter positive lead to positive battery terminal. Connect voltmeter negative lead to "M" terminal on starter solenoid. See Figure. Crank engine using remote starter switch while observing voltmeter. If voltmeter reads greater than 0.5 volt, go to next step. If voltmeter reading is less than 0.5 volt, starter feed circuit is okay, repair or replace starter.
  3. Move voltmeter negative lead to "B" terminal on starter solenoid. Crank engine and record voltmeter reading. If voltmeter reading is still greater than 0.5 volt, excessive resistance is present in positive battery cable or cable connections. If voltmeter reads less than 0.5 volt at "B" terminal, check cable connections at starter solenoid. If okay, replace starter solenoid.
