Saw no smoke while the engine fan was blowing air all over, didn't noticed the smoke after the engine was off. There is nothing else over there that would smoke so while I didn't see the source of the smoke directly I am pretty sure it was the generator. I didn't hear any arcing but then my truck needs a new exhaust system as the one on it is pretty rusted and loud. I think I need to ck the generator output and if that is ok I need a new regulator. I put one on my 65 sub years ago, it was solid state; I don't remember if I had to polarize it on not but I don't think so.
