your problem doesn't really sound like a problem with the starter to me, because the starter won't move unless power is getting to it. If it starts spinning as soon as you hook up the battery but without the key in, that means it's getting 12v at all times.
Sounds more like a short to the battery rather than a problem with the starter itself. I'd check the relay it runs on, sometimes those can get stuck closed, which would mean as soon as the car has a 12V circuit, so does the starter.
