Just bought this 1980 Lowrider Shovel from my girlfriends cousin. When you hit the front brake the headlight and taillight go out for about 30 seconds, and then you can hear a click and the lights come back on. Any ideas what could be causing this? Wiring is completely foreign to me.

 

the front brake wiring is shorted and the click is the circuit breaker, you need a wire diagram or some one who is good at tracing a short - my guess its in the switch box connected to the master

 

probably a pinched wire somewhere and it triggers the fuse... could be at the handlebar////
