My dart wont die

I don't guess I know what I'm looking for exactly. If I use a test light to backtrack, how will I know when I've found my problem? A diagram would be awesome, especially if it had the ecu box, alternator, coil, voltage regulator, ballast resistor, starter relay, and ignition switch. I'm sure that's too much to ask for but until I find such a diagram I don't see my problems coming to an end anytime soon. Thanks a lot for trying to help though. Electrical is not my expertise to say the least.
