    22.  

    Testing & Troubleshooting



    1. Perform the following electrical tests in order to determine the serviceability of the starter assemblies:
    2.  
    3. Use an ohmmeter in order to test the windings of the solenoid assembly for continuity:

      Test the resistance of the solenoid pull-in and hold-in windings in a series by measuring the resistance between the motor terminal and the solenoid case.
       
      A resistance reading well above 1.3 ohms indicates a break or fault in the winding continuity.
       
      A resistance reading well below  0.8 ohms indicates a short or ground in the winding circuit.
       

    4.  
    5. Replace the solenoid assembly if the resistance reading is extremely high or very low.

      Fig. Testing solenoid

    6.  
    7. Use the following procedure in order to test the armature assembly. Replace a shorted or grounded armature, or an armature that shows evidence of opens.

      Rotate the armature in a growler.
       
      Hold a steel strip such as a hacksaw against the armature.
       
      If the steel strip vibrates in an area, a short is present.
       

    8.  
    9. Use a ohmmeter in order to test for continuity between the armature shaft and any point on the commutator. Continuity indicates a ground.
    10.  
    11. Inspect the points where the armature conductors join the commutator and /or individual commutator segments for signs of arcing or burning. These signs indicate opens.
    12.  
    13. Perform the following procedure in order to inspect the frame and field assembly for grounds or opens:

      Inspect the field coil connections for opens between the field terminal and the connection points for insulated brushes on the field coil straps.
       
      Use a self-powered test lamp or ohmmeter in order to test for continuity or grounds between the frame and the field terminal.
       

    14.  
    15. Replace the frame and field assembly that has grounds or opens.
    16.  

    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.
