Which bit is +ve and which -ve in a cigarette lighter socket? I could put a meter on myself of course but it's cold out there.

Sort of boaty.

In a car the outside is connected to earth, usually negative, and the centre is the other yin, usually positive. How your boat is wired is anyone's guess but you've got a 50% chance of being right (or wrong!).

You could put a diode in the circuit so that the power goes through the correct way, and if you happened to plug it into a socket that was wired the other way round, it just wouldn't work.

Just a thought.
