MAD ammeter bypass question

Does nobody here follow what @72RoadRunnerGTX has posted about this bogus / red-herring ammeter bypass?
First Ive heard of it. I dont claim to be an electrical guru, or know near as much as some of the other members on here, but I did recognize my wiring frying/smoking/fizzing just as described may happen and was directed to that bypass by some very knowledgeable people whom Ive come to trust on here.
