I took electronics my last 2 yrs of high school - a long time ago. I have been involved in industrial electricity to a minor extent over the last 29 years - mostly process control, but I digress. There actually is a technical reason that positive ground went the way of the dinosaur. Seems like something to do with direction of electron flow and dissimilar metals, but I cannot remember what the heck it was. A good electrical engineer might know.

They were harder on something - points or generator or something growing green corrosion seems to fuzzily float around in my head.
