Starter Solenoid: Testing and Inspection
Starter Solenoid
1. Check the starter solenoid for continuity between the S- and M-terminals, using the 73 Digital Multimeter. Replace the starter motor if there is no
continuity.
2. Check for continuity between the S-terminal and the starter solenoid body, using the digital multimeter. Replace the starter motor if there is no
continuity.
Solenoid M-Terminal
1. Make sure the starter solenoid is isolated from the starter motor. Using the 73 Digital Multimeter, check for continuity between the S- and
M-terminals. Also check for continuity between the S-terminal and starter motor body. If either check shows no continuity, replace the starter
motor.
2. Check for continuity between the M-terminal and the B-terminal. If there is continuity, replace the starter motor.
