Testing & Troubleshooting



Correct starter motor operation can be confirmed by performing following free running bench test. This test can only be performed with starter motor removed from vehicle. Refer to Starting Specifications for starter motor specifications.

  1. Remove starter motor from vehicle. Refer to Starter Motor Removal and Installation.
  2.  
  3. Mount starter motor securely in a soft-jawed bench vise. The vise jaws should be clamped on mounting flange of starter motor. Never clamp on starter motor by field frame.
  4.  
  5. Connect suitable volt-ampere tester and 12-volt battery to starter motor in series, and set ammeter to 100 ampere scale. See instructions provided by manufacturer of volt-ampere tester being used.
  6.  
  7. Install jumper wire from solenoid terminal to solenoid battery terminal. The starter motor should operate. If starter motor fails to operate, replace faulty starter motor assembly.
  8.  
  9. Adjust carbon pile load of tester to obtain free running test voltage. Refer to Starting Specifications for starter motor free running test voltage specifications.
  10.  
  11. Note reading on ammeter and compare reading to free running test maximum amperage draw. Refer to Starting Specifications section for starter motor free running test maximum amperage draw specifications.
  12.  

If ammeter reading exceeds maximum amperage draw specification, replace faulty starter motor assembly.

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.
