  • Paczosa
  • I just bought my first 2n in Tucson, Az. Restoring back to 6v. Anybody in Tucson?
    I've got a few questions: does it have to be + ground? It had a 12v battery negative ground with a resistor but still a 6v gen & starter. Need some advise... 520-834-3992

  • Re: Paczosa
  • Restoring it means going back to original.
    Paint and all.
    The 6V pos ground can be jump started with a 12V battery if the need arises.
    Simply a case of placing the 12V pos cable on perhaps the foot peg for convenience.
    Turn on the ign switch and in neutral, then briefly touch the neg cable to the starter lug only. The engine will crank immediately, the generator will turn and also start producing the voltage needed for the ignition system.
    Generators do not need a reference voltage and that is why it is safer to disconnect them while the engine is running to check them. Alternators can cause issued when disconnected.
    Have fun with your new toy.
    Remember, if you get a second implement you need another tractor.

  • Welcome to the wonderful world of Ford N-Series tractors -you're gonna have fun! These N's will run on 6V or 12V*. Itís best to invest in the essential manuals first if you don't have them already. The I&T FO-4 Manual is like a Bible as it contains a ton of useful information on most major systems on the N's. The electrical systems changed over the years so it is important to know what setup you have before applying any power and changing out parts. The MPC has most all parts listed with exploded views, and the OEM Operatorís and Service Manuals also have a lot of good info in them. There are numerous documents in the HOW-TOís forum here you can access and download for reference as well. One as listed below is WIRING PICTOGRAMS BY JMOR. It has all the correct ways to wire an N Tractor. These Nís will run on 6V/POS GRN as originally wired or 12V/NEG GRN as long as the wiring is correct. *A 12V battery installed with no other changes will also work, but defeats the purpose of switching to a 12V battery/system. If you are going to switch it back to a 6V battery/system, I highly recommend you also wire it as positive ground. Look over the wiring carefully. The 9N (after s/n 12500) and the 2N used a 1-Wire/3-Brush generator with the round-can cutout circuit. The cutout is mounted on the back side of dash, on the lower steering box. The OEM Ballast Resistor is mounted on the back dash panel, on the RH side viewed from the front of tractor. The starter motor is a 1-Wire unit and does not use a solenoid. There is the ammeter, the ignition key switch, and the Neutral Safety Starter Push Button Switch by the shifter handle. If you adhere to the OEM wiring diagram and donít delete any components or try and take shortcuts, you will be fine. Once satisfied wiring is all correct with your 6V battery, positive ground, you can polarize the generator at the cutout. It has two wire connections, BAT and ARM. Simply take a set of pliers and momentarily arc spark the two terminals. That's it. In the manual photo below, the top ones, INSTRUCTION MANUAL; SERVICE MANUAL; and PLOW MANUAL are all in our library for free download. They and the FO-4 Manual have most everything you need to know about your 2N. Also download a copy of Bruce(VA)'s 75 Tips for N-Owners for a good guide.

  • Re: Paczosa
  • Probably does not Have to be Positive ground but that is the way Ford engineered it. On a high performance engine, polarity to the coil is much more important. Hard to say if the generator has been polarized for negative ground. If it has and you change back it will have to be re-polarized.
