Last time I took the van out (2010 Rambler 19/4 SE(based on an Elldis Avante 540)) I managed o let the electric tow cable drag on the floor causing wires to break (or wear through). So i managed to effect a temporary repair to get us home.
I have decided to replace the cable back to the van and decided to mount a couple of Wago terminal boxes close to the power supply under the seat of van, into which I have terminated the new cable. I have cut back the old cable to about 2 foot and begun to terminate this into the terminal boxes, however when stripping back the last cable on Pin 13 (earth return for Pin 9 the permanent 12v live), I have noticed that all the strands are blackened. This supposes me as all the other cables are perfect. I don't think it has been caused by water ingresses this is the only cable that has the problem and it seems to be all along the cable. I suspect over heating but the supply wire was perfectly ok. Both wires are 2.5mm
Any Electrical Engineers have any theories?
I am planning to cut and clean this wire close to the power supply plug which it feeds into and run another short piece of earth wire along side, terminating all three into a wagon to maintain continuity.
