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.

What model and year?
We have diagrams for almost everything.

I guess if a person doesn't know how all of it works it would be hard to tell woudn't it.

Start it and disconnect the harness for the ignition switch (did it die?)
Then it's in the ignition switch.

Do you have signals, wipers, or heater blower when the key off?
