Ok. This has puzzled several mechanics.I drove my car to a store, parked it, shut it off. After coming back out, the car wouldn't start. When turning the key, there is no 'click' sound, no noise, nothing. After several failed attempts to jumpstart it, nothing. I left it there for 2 hours till a friend came over to help. All he did was wiggle the negative wire to the battery, and it started! How ever. After going back home, parking it, shutting it off, waiting several seconds, I tried to start it again, nothing, its dead.I let it sit overnight, and this morning, I went out with a new terminal connector, got in it, turned the key, it started. But again, after turning it off, it wouldn't start. I changed the terminal, got back in it, and its still dead. Im lost.

If this is puzzling your mechanics, then either you are dealing with the wrong people or the problem simply wasn't duplicated when they examined it. They have to be able to duplicate the problem or nothing can be accurately diagnosed. If the car is dead at the time, it's a fairly simple process of elimination to troubleshoot the circuit but if the problem isn't present, then you can't fix what isn't broken.
I can give you the wiring diagram but it won't be any help unless you have someone that can follow it and the problem is present at the time.
