Hi everyone, it has been a while since i posted on here. Last time i was having issues with a used 1.7 i put in my car. Since then, i built a 2056 and got the car running and driving. As i was out breaking in the engine my coil vibrated loose, slid into my throttle linkage and shorted out my ignition system. The positive wire to the coil melted and combined itself with the negitive coil wire. I pulled the engine harness out of the car and fixed the two wires that got toasted, but now the car has no power to the coil when i turn the key on. I have been trying to use the wiring diagrams in the haynes manual to trace the circuit, but i have been unable to figure it out. Those wiring diagrams suck, they look like they were photo copied 3 or 4 times before they made it into the manual.
I also pulled my relay board and did a continuity test to at all the corisponding terminals and the board checks out ok. Im not sure where to go from this point. It doesnt look like there are any fuses anywhere for this circuit. There are some other electrical issues too, but getting the car running is #1 priority. I pulled the fuse pannel down from the dash and the wires that hook to the fuse for the blinkers were melted. The blinkers havent been working on the car, so somewhere there is an issue with that circuit as well. Ignition circuit first though. Anyone have any expertise in this area?? Please help. I must show these gremlins who is really in charge!!

Well, last night i was able to find the problem in my wiring. Actually it was in the ignition switch not the wiring, although I do need to replace several wires as well. All of the wires checked out good up to the fuse board, but i wasnt getting any power to the 2 black wires on fuse ""8"" when turning the key on. Testing each wire individually i determined that they were all good, but i was getting no power from after the ignition switch. I decided i had to pull the steering wheel and get the ignition switch out, so i did. I disasembled the switch and was able to see where the contact had gotten so hot it melted back into the plastic and away from the contact. Attached Image
One thing that i was quite confused by is that the 2 black wires that are supposed to be running to the hot side of fuse 8 are going to fuse 9. I was able to pick up 12v on fuse 8 when i turned the igniton on, but the 2 black wires have always been atatched to fuse 9 since i have owned the car. You may be able to make this out in the picture. Also, what is the empty relay port for?? Can anyone make out any other wiring oddities on my fuse board? There have definatly been wires added in the past. Attached ImageThanks
