Hey Hey.

As stated, I bought a 12-volt accessory plug from amazon, wired it up with an inline fuse as you would with both positive and negative cables. It's been working fine as I use it to power my tv and other items yet last week doing some work I removed the negative cable thinking it was from something else and the tv was still happily working away.

Ran some tests using a multimeter and the negative terminal on the plug was showing voltage with only the positive cable connected, there's no grounding of cables or the plug.

How ideas how its working on one cable? is the plug faulty or will they work like that? or is it a magic plug lol.

Ohh I forgot i did a video the other day
Kate.
