all of my lights and gauges were operating after installing relays, except for one brake light and one license plate light. Changed both of the bulbs, then no brake lights at all. Did a continuity check on brake light switch and it was working properly. Then all my lights and gauges stopped working except head and turn signals.
I installed relays to take part of the load off the switch and give me brighter lights.
I couldn't trace the reason for the brake lights not working. The back-up lights and brake lights are on the same circuit. I got all the other lights functioning. I tapped into an "always hot" circuit and ran a fused wire directly to the brake lights. The only problem I am still working on is the tach, gas gauge, and temp gauge are not working. I think that problem is caused by the voltage stabilizer. Could be not grounded properly or a loose wire because sometimes they work and sometimes they don't. I know those stabilizers have always been a problem. Can they be bypassed?
