When I purchased my 78 Midget the tach would work when it felt like it (jumps every now and then), the gas gauge doesnt work at all (sits on "E"), the horn doesnt work, the curtesy light, cigarette lighter and radio dont work. The gas gauge Im sure is the sending unit needing torn out and replaced. The tach Im sure has a wire that needs addressed. But the horn, curtesy light, and cigarette lighter is the one that has me stumped. The previous owner put an after market radio in with Clarion speakers yet it doesnt turn on. Im wondering if a ground wire or something in there is not grounded right. I checked the fuse box and all fuses are good and the wires there seem to have good connection. Im not so concerned about the curtesy light or the cigarette lighter, yet the horn I would like to work with some of the crazy's out there that act like they dont see me coming. Electrical I know can be a real headache and honestly I dont know where to even start. I guess I need to determine what circuit each component is on or possibly if they are all together. Any tips or suggestions?
