The only place that I know of to get a wiring diagram is a Helms motor manual. Unless you can find someone who has one, they go for 50-80 depending on the car. How about a used one on Amazon??? Are you sure that it's not the alternator? I would disconnect the plug and the wire from the back stud and see if it still drains.
