Can new wiring be pulled from the navigation station to the head and v-berth cabin? I installed new lights in the main cabin with no problem. When I installed the new light in the head I had to drill a new screw hole. After installation the cabin light breaker trips when reset. Removed the light and screws but still breaker trips. I assume the screw hit the wires, however I would have expected the wires to slip out of the way. Any ideas? Have any of you replaced the wire between the headliner and the cabin top?
