I am assuming you already checked the obvious, have you used a volt meter to determine if you in fact don't have any power at the light fixture(s), checked the bulb(s). If you have done this then remove one or more of your lights from their mounts but don't cut any wires just try to determine what color wire Marinette used in the cabin light circuit in 1966, it might benefit you to open them all so your absolutely certain of the color, you may have to pull them out a ways to get to the actual Marinette harness not to get confused with the color of the wiring on the light fixture itself. Then you'll need to stick your head into places with a bright flashlight and look for this color wire coming through a terminal strip or fuse block, sometimes the wiring could be secured to a terminal strip in one color on one side of the strip and the wire on the other side of the strip could be a whole different color, exact same circuit, two different colors, keep this in mind when you trace. If you find the fuse block test it too with your volt meter. Often something like this is a loose ground wire, check those as well. Could also be a main switch feeding this circuit is bad, because our boats are aluminum Marinette took the precautions to put switches in front of switches in the form of a circuit breaker. If you have a switch panel you should open it and look for loose or disconnected terminals. If you find what you believe is the hot source for your cabin light circuit you can perform a continuity check to test the integrity of the wiring from the hot source to your light fixture or fabricate a long length of wire with an alligator clip on each end, clip one end onto the source and the other to the light fixture, you can use this test lead on both sides of the circuit to determine if you have bad or shorted wire. If your not savvy with electrical troubleshooting or intimidated by it have someone help you that is knowledgeable. Electrical issues can seem bigger than they actually are. Hope this helps.
