I just got a new car, 51 Hudson Hornet. It looks like someone started a 12v conversion on it, maybe 30 years ago. It has an alternator, but still the 6v coil, and looks like the old light bulbs also. The wiring is mostly original, with some patching done long ago. The car has overdrive. I'm a bit leery about trying to run the OD on 12v, as the solenoid is a 6v version, and I don't want to burn it up. Anyways...I know there are still some folks driving old cars with 6v systems. I just was wondering, how it works out these days? I can get a 6v battery at Tractor Supply for a hundred bucks, vs a 12v battery at walmart for $50. I don't have a generator or regulator, so I'd have to find one, or else spring for one of the new 6v alternators they sell (which would probably be the smart way to go). I know generators and mechanical voltage regulators still give as much trouble as they used to, as I've had them on a couple other cars recently. Thoughts?
