Hi
37 Chev 1/2 ton
While adding brake lights, I discovered the brake light switch on the end of the brake cylinder wasnt working when brake peddle depressed.The feed wire shows 6 volts the other side 2. if I manually connect the two wires the brake lights work.
I also tried a brand new pressure switch. This didnt work either
Is there something else I should be checking
(note brakes work well just no brake light(
