Hi Govert, Yes the light goes on when you turn the key and goes out when the car is started. Do you recall if a "hot wire" attaches to one of those B+ (battery positive post?) terminals?
Whoops! Sorry to trouble you with the question. I discovered (and then remembered) what happened. When I took the alternator out and sent it back I used electrical tape to cover the hot wire to the rest of the bundle of wires so that it wouldn't short against the body of the car while I waited for the new alternator. It is now connected and running fine. Thanks again.
