Hans,
Well, the metal erosion/deposition that takes place across contacts
is a different situation, I think. As for the actual wire wearing,
that I don't understand. Why should a piece of copper care which
direction electrons are flowing in?
I have an MGA and a Magnette and they are both positive ground and I
don't see any difference either. (If you're reading this, sorry
Barney. I know this makes you think I'm insane.)
In any event, my quest for actual scientific data continues.
