Starter Solenoid: Testing and Inspection

Starter Solenoid Component Test

1. Disconnect the battery negative cable.
2. Using the Digital Multimeter, check the windings of the solenoid as follows:
^ Measure the resistance between the starter motor ground terminal and the solenoid case. The resistance reading should be approximately 0.95 ohms.
^ An extremely high resistance reading indicates a break or fault in winding continuity. A very low resistance reading indicates a short or ground in the winding circuit. Either condition is cause for installation of a new solenoid assembly.
