Changing ground + to -

Thanks to all who responded to my previous post. My 1916 with a 1921 engine is positive ground. To change it to negative ground I plan to: 1) reverse the battery cables 2) polarize the generator by briefly touching B+ to the field terminal Should I disconnect the generator wire while I polarize the ...

Re: positive to negative ground

The starter will be fine. I've used 12 volts negative ground systems with several old six volt positive ground starters. But now that I think about it I'll need to reverse the wires on my ammeter.

positive to negative ground

My Model T (1916 with a 1921 starter engine) came to me wired with positive ground. I would like to change it to negative ground (just because that's the way Ford did it). Advice please: Can I simply polarize the generator by putting B+ to the field, reverse the battery cables, and go? Will the cuto...

Re: negative ground?

My 1915 runabout is 6 volt positive ground. Of course the chassis had no polarity when the car was built, T's didn't have batteries until 1919. Whoever installed a later engine/starter/generator in my car years ago apparently decided to make it positive ground. This is my first T - I assumed all T's...

negative ground?

A friend just bought a nice '24 T runabout, and older restoration. The battery is connected for negative ground! It seems to charge and work OK. Does anyone know why this might have been done? How can we change the generator and/or cutout to bring it back to positive ground?

Whippet radiator shells

What makes Whippet radiator shells so popular for Model T's? Do people use the Whippet radiator also, or just the shell? Is it just that the Whippet shell just happens to fit a T radiator very well?

high speed clutch chatter

I'm fairly new to Model T's. I have a 1916 runabout with a 1922 engine and trans. Since I've owned it the clutch has chattered a bit when going from low to high. I have only driven it a little bit (maybe 50 miles) but the chatter seems to be getting worse. Should I try adjusting the three screws on ...

Just a thought: The rear looks like it has a lot of paint on it. It may help to strip the old paint and give it a fresh thin coat.

Re: tube question 30x3-1/2 demountables

Over the weekend I installed my new rear wheels and rims. Everything fit fine, I have only minimal runout in the rear. I also looked more closely at the fronts. I realize now that most of the runout is due to the tires, not the wheels or rims. One front felloe/rim combo runs out 1/2-inch side to sid...

Re: tube question 30x3-1/2 demountables

My tubes are "Custom Classic" brand. The stems were noticeably offset and leaning toward the blue stripe side when inflated before putting them into the tires, but all were tilted different amounts so it does not seem to be intentional. Lang's told me they don't know what the blue stripe signifies. ...

Thanks to all who commented. I don't remember the brand of the tubes, they came from Lang's. The holes in my rims are slightly outboard of center. Inflating the tubes outside of the tires showed me that the stems were offset in varying degrees toward the blue stripe side so I installed all 4 with st...

I just had my wheels re-spoked my Stutzman. They are beautiful, but now it's time to finish them. What color is correct for 1916? Maybe they were simply painted by Ford, but I'd like to show off my beautiful spokes.
Should I stain them first, then clear coat - or use a tinted clearcoat?

I just got my first T and have a lot of learning to do. It has a Ruckstell. I have seen original Ruckstell ads that say an advantage is that it has a neutral, which makes cold-weather starting easy without jacking up a wheel. But Chaffin's literature says there is no neutral unless the gears are bad...

Thanks to 1922Ford for the personal reply, and to everyone else for your forum replies.
I have already ordered the float material from Lang's. I'll see how well it works.
The good news: it's very easy to access the sending unit on a '49 Plymouth, so no big deal if it sinks again.
