Just what the title says, I'd like one that works as mine is trying to pump 17 or 18 volts into my 12 volt battery and it also has a tendency to kill my battery with a slight draw. My alternator has a round plug with 2 pins pointing up and down and 2 pins facing left and right. Call me at 305-915-3093. I am located near Ft Lauderdale International airport, so the closer the better.

Thanks,
Stephen
