  • NAA Starting issues
  • I have a 54 NAA 6v pos ground. If the resistor goes bad would it cause a tractor to run if pull started, but not start with starter switch? Battery is good, engine cranks just won't start. Points are gapped correctly. Runs great after a pull start.

  • HiYa Dan. Where are you seeing a resistor in the circuit? There is no such thing on the NAA. A 6V battery does not mean it is wired correctly for the system, positive or negative. Get out your Essential Manuals and use the wiring diagrams to diagnose the wiring setup. Disconnect battery first and use a VOM set to continuity not a test light. Don't go by wire colors, don't assume. Take no shortcuts. BTW, it is much easier to jump start your tractor with your 12V car or truck, no need to pull it around the yard. You have to know the correct way to jump start it though, it matters.

  • In all the confusion I had forgot to mention that 2 winters ago with everything just as it is now the tractor would start on its own power. That's why I'm confused about it not starting now. Haven't done any wire changing. I didn't actually mean resistor, I meant voltage regulator.

  • The first thing you should do is take the battery to a local shop or store and have it tested on their bench equipment. If your tractor sets for 10 days or longer it will begin to lose electrolyte and diminish charging capability. To remedy this, many of us get a float charger unit (not a trickle charger)and keep the battery constantly maintained so it is 100% ready when you need it. The DELTRAN BATTERY TENDER JR. is one of the better units. If battery tests bad -it won't sustain a full charge under load -then a new one is in order. While battery is out and disconnected, verify the wiring is all correct. Get a copy of the I&T FO-19 Manual. Trace wires with a VOM set to continuity, not a test light. Tractor sat for 2 years -no doubt it is dead unless maintained.

  • Re: NAA Starting issues
  • If you are saying it has set for two years, I would have to suggest a battery test. Probably take it to a auto parts store where they can do a proper test.

    Next I would look at a dragging starter.

    Good Luck,

    Jack

  • Easy peasy.....jumper the resistor & see if it starts.

  • Re: NAA Starting issues
  • A guy I know wanted to sell an 8N to me. We pull started it and it sounded pretty good when running. I don't recall oil pressure. Any way I asked if a compression test had been run. He said no. Later we cranked the engine over and had numbers in the 30 range. I said no thanks. You might run a compression test. I have heard marvel mystery oil in the cylinders loosened stuck rings and improved compression.

  • Re: NAA Starting issues
  • I did notice when running that I had good oil pressure. It was over 40.
