[Mgs] Positive ground = more rust?

[Steven Trovato]

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.
