Brake Light Switch: Testing and Inspection

CHECK THE STOP LAMP SWITCH
1. With an ohmmeter connected to the stop lamp switch terminals, check for continuity.





2. If there is no continuity when the plunger is depressed and there is continuity when the plunger is released, the stop lamp switch is normal.
