Tailights grounding out, help! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok I had my bed lifted off my frame to test fit some parts and I hooked my lights back up and checked them and nothing! But, my led bar and tag lights work but no tails or reverse, so I got my test light out and I have power to my connectors but I scratched one of the housings by accident and saw it light up so it's grounding out. I checked for open wires and all and have found none and none of my wires for really touching the bed (Where its grounding out at) so my whole bed is energized and I can't find where!! Help.

grounding out????? no your bed is not grounded thats the cause of your lights not lighting run a ground wire from one of the cross sills of the bed to the frame crossmember and your lights will light

If it happened after you had the bed off make sure you also have a good ground from the engine block to the frame. I had a similar problem when I realigned my bed.

As cdowns says, I put a ground cable from the bed to the frame and another from the engine block to the frame. This way I made sure I was grounded back to the battery.

If it was doing it before you moved the bed, it may also be your light switch.
