I have a question for you electrical experts, probably Neil can answer this but I thought it would be good to ask on the forum instead on the phone.
What is black wire caused by on the ground side of a 12v system. I have never really understood what it really is or the cause. I believe it increases resistance but that is about all I know about it and I'm not sure of that. I have seen a bit on my boats 40+ year old wiring. I have replaced a bit of wiring when the pig tails left after replaceing something electrical are to short to tie into. The wiring leaves a bit to be desired on most old production boats like mine.
