I have a 1981 Chevrolet El Camino. When I put it away for the winter my headlighhts worked but when I brought it out this year my headlights and tail lights did not work. I went through the fuses and two of them dont have power at all. I think the switch works off grounds cause I tested it and it seems to be working I think. I could fix it with a diagram but the parts stores in my area dont have the books for it. Any and all help will be greatly appreciated
In the case of headlamps and tail lamps, The switch supplies the current through a relay.Relays tend to fail when set up too long. The relays should be under the hood. The ligt switch cannot handle the current load required and could be damaged by overheating if wired direct to lights. Look for the relayThe dead fuses should be identifie near or at their location if not under the cover if so equiped. Food luck. Remember, each lap has its own grounf, including the relay. So, your batt eng ground and engine to body grounds are very important.
