I want to switch my H to 12v. Took 6v. gen to electrical shop and the guy told me it wasn't very practical to rewind 6v. gen to 12v. What other Farmall model would have nearly the same size generater that i could look for in 12v.An M maybe?? Any help would be appreciated!!

Stay on track with the 12V conversion its the way to go. 6V systems require a lot of current and results in significant voltage drop at every connection so how many of the 6 Volts reaches the starter?). This is why power companies transfer power at very high voltage. I had 2 6V generators from Farmall Bs converted without a problem. Take them to another generator man. It might cost a little but it will be done right. Don't try and regulate a 6 V generator to 12V.

Good Luck

Ben: Would you please comment on why it is ill advised to regulate a 6V Generator for a 12V output. I converted a "H" to 12 V using this method approx 12 years ago and a Super "A" just a few months ago, both seem to work just fine. With the exception of the 12V slamming the Bendix into the starter ring with some force,I have not experienced any problems with the conversions. If this modification is in some way detrimental to the electrical system as a whole I would appreciate knowing so that I can make changes. I did the "H" due to lack of space under the cowl and the "A" because of the ease and cost. To the question as to why one would convert from 6V to 12V. Personal choice and it makes life much easier.

Les - I am not a generator man, but I was told by the place I got my generators converted that just regulating a 6V generator to 12 would give you a marginal generator. My guess is that to charge a 12V system I think you need around 13.8V and that maybe a 6V generator would only produce this at high rpm or have low current charging capacity?
A good generator shop I'm sure could explain. The shop I went to also cautioned about staying with a 6V starter due to bendix gear smack. Some have problems with it - some don't.

Dave G: Thank you for your comments. I did experience Bendix slam as I said in my post, I had the "H" starter rewound for 12V. I will have the one on the "A" rewound first time it destroyes a bendix. After requlating the 6V gen to 12V, both systems are charging at 13.46 to 14.92 according to need. I am not RPM counter equipped, but the coming in speed after modification seems to be about the same as it was for the 6V. Most any time I am using the tractors they are operating in govering range. One has the same problem with the starter reguardless of the 12V source.

Ben - There's lot's of Delco 12 volt generators that are nearly the same size as the old Farmall 6 volt. A generator from any late 50's/early 60's GM car, or most any 12 volt tractor with Delco electrics (IHC, Deere, Oliver, etc) should easily fit up.

M's had 6 volt also. Easy to convert to an alternator(check archives for Bob M description) Have heard you can put a 12 volt regulator on a 6 volt generator and it will work. Someone said the generator doesn't care what voltage it turns out. Have never tried it. I converted my SMTA to 12 volts and used an alternator. I had an old chevy 12 volt generator that would have fit with slight shimming
