Wookie, yes Lucas, the prince of darkness. Plus that weird you brits thought up, Positive ground, ha.

Most U.S. cars were positive ground until the mid to late 1950s. I seem to remember a model or two hanging on into the 1960s.

I have a distant memory of being told the change to negative ground came along with the change to 12 volt systems on American cars

That is my recollection as well.

That is correct Scotty (with British cars at least) and generally coincided with the change from "Dynamo" to "Alternator"
