I always seem to sound like Uncle Albert (Fools and Horses) but years ago... (not durin' the wowa!) my 1955 A30 was wired as Austin intended +ve earth. Most cars of that age were the same, but there was a trend, which continued, towards -ve earth, and I was led to believe the change was intended to reduce rusting. Can there be any truth in that? The theory as explained to me was that the atmosphere naturally had a -ve charge, thus a positively charged car body would be permanently under ionic attack.
I have no idea whether there's any sense in that or whether I was told a load of BS, anyway that's what came to mind reading this thread, although there's no relevance there is a "connection". Ouch!, what a lousy pun...
