Ive been in the mood to post pics lately. Was cleaning out my shed saw my light box and thought Id share it with you guys.
Last fall I was doing work for a hell of a nice guy. He had me do some welding on his shaker, liked my work and he kept me busy in my free time until winter came. He bought a low bed trailer at an auction and it had some wiring troubles, (light-mares!). This unit has a detachable gooseneck so it had an electrical plug and glad hands at this point. I wish I took pics at that time, but I didn't have my new camera yet. Anyhow It would have been damn near impossible to figure out without a few tricks up my sleeve.
I made this light box to isolate each circuit, just hooked it up to the battery on my pick up, checked the draw on the studs with my snap on volt meter test light. I tested the cord with my blue point light cord/ plug tester, then left it at the goose neck after that. This trailer had 3 junction boxes on it.
The rear light bar was crunched, and when I started to take lights out they fell into pieces. I started there. I rebuilt a light bar for him, all new wiring and lights. Still had problems. Started at the front plug and worked my way back. The first junction box had no power on some circuits, traced it back to about a foot behind the front plug, cheap *** connectors with no shrink tube. junction box fell apart and all the connection inside pulled apart. Replaced wires going to lights, some wires were even missing! I found brittle and broken wires all in the harness. Between the welding and light problems I spent 4 days on it. If it were earlier in the season and I wasn't laying in water in the rain I would have maybe thought of running new wire the whole way along, and added jumpers from ground to the frame at the J boxes. I learned a lot by the end though. View attachment IMGP0292.jpg View attachment IMGP0293.jpg View attachment IMGP0294.jpg View attachment IMGP0296.jpg View attachment IMGP0297.jpg
