If the other end of the wires went to the correct place and the switch was off, that would not drain the battery. As I posted, it does not matter which wire goes to which terminal on the switch. Trying to answer without being misinterpreted. Does that answer?
The sticking voltage regulator contact could cause it or other ignition malfunctions sticking.

Did you see the post that I linked, battery draw test??????
