I'm not sure. Kaiser ran a positive ground through 1955, but I believe
that Dodge may have gone a few years later..

What was the last US production car to use a positive chassis
ground, instead of a negative chassis ground like seen on modern
production cars?

A little off the track, but GM's buses were positive ground until they
introduced the "fishbowl" types in late 1959.

The positive ground was abandoned with the introduction of 12 volt sys-
tems. 1955 was pretty much the last use of 6 volts in all American cars.

I'm not positive (no pun intended) but I think that the last (+) ground
american cars were the 56 Fords.

Not a car, but Mack Trucks used positive ground systems into the mid
70's.

It's possible. Some references show the Ford 12 volt changeover in mid
year '56 and some show it as the beginning of the model year.

Ford and Chrysler both changed to negative ground in '56 to accomodate
transistorized radios. The independants Mostly used Delco electrics so they
were negative ground. Probably the last holdout was Powel, a very nice
looking
pickup built on pre '55 Plymouth chassis. As best I can remember, Powel was
in production untill sometime around mid '57.

I'm not sure POWELL really qualifies as a new production truck, as they
were built on a reconditioned chassis.

I've personally had contact with two of these interesting trucks. They
were built in Compton California, and were among the first truck that rode
and handled like a car (by virtue of the fact that they were built on
Plymouth passenger car chassis).

Concerning this issue. I heard the reason car makers went to a
negative ground system was because with the positive ground systems,
car's would NOT rust. Something to do with a positive ground system
repels or something. Is there any truth to this?

In other words, the makers wanted people to buy new cars rather than
driving their old ones til the wheel fell off.

It worked for boats, that why the British Navy required British autos to
have positive earth in case the navy wanted to use the motor in a boat. The
British Navy was powerful at home them. I don't know if reduces rust on
cars but owned several MGs and none of them were rust free.

I think positive ground systems were used on British cars well into
the sixties. Lucas systems, of course..... Since some car
manufacturing countries in Asia, like India for example, are building
slightly developed versions of old British models they may still have
positive ground systems, with or without included rust.

I think it has to do wither or not the electrical engineer was taught
conventional or electron current flow.

Conventional uses a negative to positive current flow.

Electron uses positive to negative current flow.

Regardless of what theory you profess the current gets from point A to
point B just fine.

Gee, I don't think the sheetmetal much cares which way the electricity
goes. As for positive ground staving off rust, ummm? There sure were
a lot of rusty old cars around when I was a kid in the 50's.

I drove the Mack Diesel trucks many years ago. All of them were positive ground.
None of them rusted apart. If positive ground rusts automobiles, positive ground
should rust trucks. I believe the rust problem has a lot to do with the quality and
preparation of the metal before the priming and painting. I drove over beaucoups of
snow covered roads that had beaucoups of salt added. When I got home, the truck was
washed from bottom to top, still no rust. As I mentioned in a prior post, I was
told the reason for switching from positive to negative was because some engineers
thought better ignition was possible if the spark jumped the plug gap in a certain
direction. EOR

When I took DCC circuits, I finally learned what the difference
between conventional and military was. It seems that Ben Franklin had
two choices. Now I'm rusty about all this so please help me out.
He could have chosen positive ground or negative ground. Is the
military which is the Ben Franklin's wrong choice, positive ground?
And thus conventional is negative ground? Or is it the other way
around?

Doesn't all this matter as we become more computerized. It's simply
using the same language; that bilingualism doesn't work in DCC?

Triumph sports cars (TR-4, Spitfire) were positive ground until about
1965/66.

NOTE

POSITIVE GROUND CAN TURN METAL SURFACES INTO _ ELECTRON SINKS,
this makes fuels and gases more explosive and can result in better fuel economy

We study water fuels and by have positive earth we can make the gases have more forces and be explosive instead of implosive

If I had to bet money I would say this is the reason also doing that can strengthen metal or protect from degradation by gases or air etc
