Good call to replace all the wiring. That's how I would have done it too.
Yeah once the wires go green it’s gone bad
But it did take a bit of time to figure out the wiring fault
@ I thought your diagnosis and eventual solution was very methodical. That tester is a nice tool. Never saw one before.
When I has the Passat, it had a trailer plug,so I used to plug all the trailers. Even if they were pulled with a tractor, as I knew it was the only vehicle with a 100% working trailer plug . So if the trailer lights All worked ok, then I knew it was the 4x4s or tractors at fault, as I didn’t trust any of the tractors. You could be going through till the trailer wiring for hours and eventually figure out it was the tractor that had the wiring fault 🙈. Really need to put a trailer plug on the TT now 😅
Bad ground somewhere along the frame. It's a well documented problem with many newer boat trailers, where wiring is fed through the frame tubing.
😲 I just don’t know why the trailers chassis is earthed when the lighting cable itself has its own earth and is far superior. Like the earth on the chassis of the trailer has to travel though the rusty trailer hitch and may also have grease on the hitch … so why and what’s the point of earthing the trailer chassis . It just seems so pointless to me
