Thanks everyone for your replies, to answer a couple of questions and to ask another, the tow vehicle is fine works well with my other trailer that I just wired.
I did not see any bare spots in the brown wires, not to say that there isn’t but how could the brake lights and signals work fine off of the same feed?
That question in it’s self may have answered the question, if the feeder wire (hot wire) doesn’t show a problem with the break and signal lights then there has to be a short in one of the lights, on the running light side of things, right????
I am no electrician
so thanks greatly for any and all help.
