This is advertised locally and if so would be news to me. Before I say it ain't so, thought I better consult the GJ expertise. Have any of you ever seen one? jack vines
GM was the first to use 12v in 1953 with Cadillac, Oldsmobile, and Buick. Probably just an early conversion to 12 v.
Without seeing the ad you're seeing, we can only guess.... but it's likely that the person selling it is clueless.
As far as I know like previously mentioned. 1953 for Cadillac, Buick, Olds. 1955 for the rest of GM, 1956 For Chrysler, Ford and the rest of independent auto makers. 1950 Plymouth sales brochure only mentions a 6 volt 15 plate 100 ampere-hour capacity battery.
If its the one out of Careywood. It looks like a conversion, stater solenoid bolted to the inside wheel well. New style wiring connectors going to a number or locations. A 15 dollar off the wall parts store positive battery cable they have grounded to the top of the head. Quite a bit of filler in the rear quarter it looks like. Seems over priced to me.
That's a 1500-2500 car tops with that amount of body damage/issues. I can almost smell the interior through the internet...
No pictures of the "factory" 12v engine bay. But glad he spelled out his plan for the paint, it all makes sense now.
The story I was told, everyone was 6 volt positive ground and it was the ideal way to go. Chevrolet never did like + ground and it was a sort of battle between all the major automobile manufacturers .... They all wanted some sort of consistency for aftermarket parts like radios etc.... All the manufacturers thought + ground was the better way to go ... chebby never agreed. Then in 1955 they came out with the 265 sbc? ..... They dominated the market after that and all the others just fell in line and followed Chebby with negative ground. Thats my story and sticking too it .... + ground rocks and chebbies suck.
That is neat, I know with 53 being the 50 year anniversary. Introduction of the corvette. Fiesta, skylark and elderado lines all launching. And the main marketing of the 12 volt system. But it isn't until 55 when the sbc came in, that 12 volt 2 years later became the go. For the rest of GM. A year later everyone follows. Makes you really wonder about the positive to negative ground set up and how things might be different.
Is simply how my Uncle explained it to me who lived through that time period. Many argue that positive ground is better .... GM simply was not going for it ....
I mean....if I still had my old avalanche I'd have willingly traded for this car. I hated my avalanche lol
https://mechanics.stackexchange.com...the-tradeoffs-for-positive-vs-negative-ground As for the seller, he probably has a 440 hemi stashed somewhere too. I still browse CL. I hate FB and how they are a data mining company with "neat perks" for those who use it to attract more usage. In my experience, the crazies who were once the bane of CL have gotten much worse on FB. CL lost big time because they started charged for listing cars. It's not the charge, it's the data mining they went to. They require personal data to pay. Don't tell me that the anonymous way is worse, look at FB and having to log in, but the issues are at least as bad if not worse with a name tied to the ads. Yeah, you can make up a fake profile, it's still all to get info from 'users' for the megacorp.
