Testing & Troubleshooting



Before removing any component of the cranking circuit, check the following:



Inspect the battery and cables.
 
Inspect the wiring for damage
 
Inspect all connections to the starter motor, solenoid, ignition switch, battery and all ground connections. Clean and tighten as required.
 
Inspect the starter motor and ignition switches to determine their condition.
 

If the battery, wiring and switches are in satisfactory condition, and the engine is known to be functioning properly, the starter may be at fault.

Voltage Drop Test

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

  1. Disable the ignition system by unplugging the coil pack. Verify that the vehicle will not start.
  2.  
  3. Connect a voltmeter between the positive terminal of the battery and the starter B+ circuit.
  4.  
  5. Turn the ignition key to the START position and note the voltage on the meter.
  6.  
  7. 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.
  8.  
  9. Connect a voltmeter between the positive terminal of the battery and the starter M circuit.
  10.  
  11. Turn the ignition key to the START position and note the voltage on the meter.
  12.  
  13. 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.
