Testing & Troubleshooting



Voltage Drop Test

NOTE
The battery must be in good condition and fully charged prior to performing this test.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disable the ignition system by unplugging the ignition system fuse. Verify that the vehicle will not start.
  4.  
  5. Connect a voltmeter between the positive terminal of the battery and the main terminal on the starter solenoid from the battery.
  6.  
  7. Turn the ignition key to the START position and note the voltage on the meter.
  8.  
  9. If voltage reads 0.5 volts or more, there is high resistance in the starter cables or the cable ground, repair as necessary. If the voltage reading is ok proceed to the next step.
  10.  
  11. Connect a voltmeter between the positive terminal of the battery and the terminal on the solenoid leading to the starter.
  12.  
  13. Turn the ignition key to the START position and note the voltage on the meter.
  14.  
  15. If voltage reads 0.5 volts or more, there is high resistance in the starter. Repair or replace the starter as necessary.
    NOTE
    Many automotive parts stores have starter bench testers available for use by customers. A starter bench test is the most definitive way to determine the condition of your starter.
