Starter Solenoid: Testing and Inspection

STARTER SOLENOID
Make sure that the starter solenoid is isolated electrically from the starter motor. Check for continuity between solenoid S-terminal and solenoid M-terminal, and between S-terminal and ground (starter frame and magnet). If there is no continuity, the following conditions may exist:
- Open wire; replace starter solenoid.
- Ice, dirt or other foreign material preventing contact; service as necessary.

SOLENOID S-TERMINAL CIRCUIT RESISTANCE
Check the resistance of the entire S-terminal circuit, including all the switches, wires and connections. Resistance should be less than 0.08 ohm.







SOLENOID M-TERMINAL
1. Check for continuity between the starter solenoid M-terminal and the starter solenoid housing.
2. If there is no continuity, replace the starter solenoid.
