  • 6 to 12 Volt Conversion
  • I'm looking to convert my NAA to a 12v system. I wasn't sure what all (if any) wires or gauges need to be changed also. Thanks for the info.

  • I used the attached for reference to convert my 641 and my 860. It was the only reference I found that also gave what wire size to use for rewiring, terminal size for connectors at each end, how to add a volt meter if desired, and how to test the conversion with a test light when done. By using the marine grade 10si alternator, there is no need to rev the engine to excite the alternator.

  • What is it you hope to gain from a 12v conversion?

  • Bruce, the way you go on endlessly, I keep looking for an article on a THREE VOLT SYSTEM that will double the horsepower and put new paint on. So much NAYSAYING.

    It's a hard job, but somebody has to do it. ;)

  • Re: 6 to 12 Volt Conversion
  • When I converted mine, i hoped to gain better and more reliable charging, I got tired of vr failing and generator failing..Life is good with 12 volts, not all people desire to stay 6 volts. for me the TIME to do it was when I needed a new battery anyway.

  • Re: 6 to 12 Volt Conversion
  • I've NEVER had a VR fail, never had non-charging issues with my '48 8N 6V/POS GRN system and it ALWAYS started in sub-freezing weather to plow snow with. As I always say, 99.98% of these issues are due to incorrect/mucked up wiring and failure to maintain basic PM. 5 or 6 reasons why to convert to 12V, a million ways not to. Your tractor, you can do anything you want. Just be sure whichever way, it is done correctly.

  • Apparently it is most important for everybody to know that the *A* team thinks folks who want 12 volt systems are sort of a knuckle dragging sub-culture.

    If you can't be helpful.....

    I'm glad you're not telling how to vote... Just sayin'...

  • Yep, we offer pro-active advice, not telling people what to do. Unlike trolls like you who never post positive stuff, only stir the pot.

  • Dan-
    Welcome aboard the NTC! You'll find a wiring diagram in our HOW-TO's forum -see LINK below as well as many other useful technical documents you can download for FREE. Scroll all the way the bottom to see the NAA 12V conversion. There are about half dozen correct ways to switch over, and a hundred or so incorrect ways often done by fellas who have no clue what they are doing. There are also about a half dozen good reasons fort switching and a half dozen reasons why not too. First, we all know it is your tractor and you can do anything you want with it. Switching a 6V/POS GRN system over to a 2V/NEG system is often thought of as 'fix' for a non-starting/non-running tractor. It isn't. If it doesn't start now on 6V it isn't going to on 12V. You also need to know that 99.98% of all non-starting issues are due to incorrect wiring, regardless if 6V or 12V. Most of those issues are due to an incorrect 12V switch over job. Find copy of 75 Tips For N Owners, and download copy as well as wiring pictograms to start with before you decide anything. If you are having non-starting issues now, look at this electrical system wiring diagram from the Operator's Manual and verify what you have is correct for a 6V/POS GRN system. A lot of issues are also due to an old battery that won't sustain a charge anymore. If it is 5 years old or more, chances are it will no longer hold a charge as the electrolyte is all depleted. Your local starter/alternator shop can bench test it for FREE usually. Start with these points first.
