I am about to replace my battery. The 6-volt did a good job in warmer weather, but in winter cranked slowly even when fully charged. It usually starts, though, as long as I'm tuned up and otherwise set. A friend told me to try an 8-volt, which I'd never heard of, but they assure me at the shop that I can get one for the same price as a six volt. In fact, they say that the 8-volt will work better. I am wondering if (a) it will work; (b) it will cause more problems; (c) if I have to re-set the voltage regulator in some way if I do it, or do I just pop in th enew battery and go.

Any suggestions?

Thanks for all the comments. I will be happy to clean 'er up and stick with the 6-v and stop listening to the wagging-tongued know-nothings. At least I knew enough to check it out here!

Can you really jump start a 6v with a 12 volt? I didn't think that was wise.

I just last week changed the cobbled 8N that I bought from 8 volts back to 6 volts. The reason it had been changed over was that the starter bushings had worn out and the armature was dragging on the field shoes. You could start it by jumping with 12 volts but I had a couple of old 6 volt starters that I had stuffed under a work bench for years just in cast that came off a 49 through 53 Ford flat head car engine so I took the front and rear ends from one of the car starters that had good bushing and used the armature and fields from the N starter and when I put it back on the tractor with a new 6 volt battery it started just like the N is supposed to start.

Get a rebuilt 6 volt starter and a new battery and stop having trouble starting.

Hi Don,

Would you like to burn points, coil, lights
generator, voltage regulator, dollar$
If your answer is yes...put a 8 volt battery

A healty 6 volt charging system and battery will
give good service.

Just my 0.02 cents

Much has been written in the archives.
A. Depends on your definition of "Work" (Your charging system will not like it"
B. Yes.
C. Trying to reset the voltage regulator is a risky endevor since they are not made to be be adjusted. Although it could be done by playing with the gap and springs.
Fix the problems that cause your tractor to start poorly in cold weather.
Happy Motoring

Why do they even make 8 volt batterys? What normally would use one? I have seen 6 volt, 12 volt, 24 volt systems and now there is talk of a 48 volt system.

They were originally intended for the marine market. I had a 6 volt Chris Craft that I converted to 12 volts. This was due to the current demands when idling in long no wake zones. I am not an advocate of changing tractors because these current demands are not there in most instances.

Yes you are correct as to the marine thing. Yachts of the day, some Navy, and work boats used 32V systems for starting and ships service. Some basic shrimp trawlers still use 32V today. On trawlers 8V batteries were in banks of four and provided for starting, lighting and a refrigerator. Also 3 8V would give you 24V which smaller yachts and day work boats used. The only commercial non-marine application of 8V batteries that I can recall is the Murphy Diesel engine which also used the 32V system as in NW Engineering cranes.

Get the 6v clean and tight, with good cables and wiring. If that doesn't do it, convert to 12 v., or start the tractor on a 12v jump and run it on 6v. Forget the 8v. My $.02

I am with claus on this one - my son was playing with the lights on my 2N and left them on. After I saw this and turned them off (1/2 to 1 hour on - best guess) I tried starting the tractor.

It cranked v-e-r-y slowly, but on the third "rrmpff", off she went, running like nothing was wrong at all.

IMO, if the 6 volt system works, don't mess with it. As Dell has pointed out, our ears are used to the spin of our car's 12 volt starter and anything else seems too slow. But if it is fast starts you want, go with a good 12 volt conversion.

Just adding the 8 volt battery will increase the voltage to your coil and may cause damage there.
