Update: I touched the first and third screws nothing happened. No spark or arc, nada. I had a screw driver tip on the first screw and another screw driver tip on the third and then touched the two screw drivers togather.
I also removed the screw and cleaned the wires attached to it. Does the third screw, the one closest to the front of car, have any wires leading to it? Mine only has a female end of a wire connector attached.
Why wouldn't I at least get an arc or spark when touching the screw drivers togather?
