If it is not the footswitch you are likely looking for an open circuit (broken wire) not a short. If it were a short you's be tripping a circuit breaker for the lights and the low beams would not have power when you switch back to low beams until the breaker cools off enough to reset. (I'm working from memory that says there is a single breaker for high and low beams, not two breakers, one for each set of lights)Thanks. I have ordered a new footswitch. Hopefully that will fix the problem. If not, I will have to trace the wires to the headlights to find a short.
Headlight switch. Also check you back running lights when the highs and lows don't burn. There may be a problem with the connector or with the headlamp switch itself. Clean everything quite well with electronic cleaner, and lube with Dseries dielectric lube, or the clear sparkplug boot dope you get at the autoparts counters.I have a 69 XR-7 and when my low beams are on and I push the foot switch for the high beams, the high beams do not come on and the low beams go off so that I have no head lights at all. Can anyone help me with this problem?
