Check it with a meter to be sure though, because as I said I've seen both.

Status: offline 		The wire connected to the center should be the positive lead. I would expect it to be the one with the stripe but, as already stated, a quick check with a VOM will confirm which wire it is.

Status: offline 		the solid black wire is the negative and the black one with white stripes is positive, i saw the same wires on a different charger and thats the way it matched up to the battery so i charged the glow plug igniter and its fine.

Thanks, Daniel
