Hi all, I'm connecting a powerlet plug to my battery charger so I can just plug it into my bike as a means of keeping the battery topped up.
Now because the charger only came with alligator clips, I've cut them off and now I'm ready to join the wires to the powerlet plug. My problem is I don't know which part of the plug is live and which is the neg part.
Can one of you electrical gurus tell me whether it's the central prong or the surround part of the plug which is live ???

Cheers to anyone who can help me prevent some fireworks happening
