I bought my 715 with a small block Chev and hacked up wiring. I've got it rewired (with a key switch replacing the on/ off and start button) to get it started, running, and the lights working. Only problem is the head light switch must have a circuit breaker in it or something, because after about 15 seconds the lights go out and 15 seconds later they come back on. I can here a clicking noise from inside the switch every time it happens. Any help on fixing this would be great?
