  • Electronic ignition
  • I have an Naa, 6 volt, with electric ignition. I have been cleaning it up and now I can't get the timing set. Is there a trick? I set the flywheel at 8 degrees before tdc, point the rotor to cylinder #1
    Am I missing something. Any help would be appreciated.

  • Re: Electronic ignition
  • Often it's the simple things. Forgive me if this is too simple, but a recent email chain ended up with the guy didn't realize the rotor needed to be pointing at No.1 AFTER the distributor was all the way down. I incorrectly thought that was too obvious to mention. As has already been mentioned, initial timing is 0 degrees. Hope you are doing this inside, with enough heat to get above freezing. I've put wires in cap wrong way around more than once. I don't know why that seems so easy to do. Once the distributor is bolted down, I bump starter to confirm distributor rotation even when I'm sure I know which way it goes. That seems to help me get the plug wires in the right holes.

  • Re: Electronic ignition
  • I am inside, thank goodness. The plug wires are in the right way, that is not it. So I pulled distributer and set flywheel to 0 degrees, reinstalled dist and put flywheel at 8 degrees,rotor pointing at cylinder 1 wire. Not starting, clearly I am missing something. Not a mechanical whiz, not a novice either.

  • Re: Electronic ignition
  • Here's where you went wrong:
    "and put flywheel at 8 degrees".

    Set flywheel at 0 degrees
    Install distributor with rotor pointing at no.1
    Tighten distributor clamp

    With engine stopped, initial timing is 0 degrees. After engine is running, at well over idle RPM, you can use a timing light to check if the mechanical advance has cranked it around to 8 degrees before. I don't bother with that. If initial timing is right, and engine seems to run right, assume mechanical advance is working, and move on to the next task on my list for the day.

  • Re: Electronic ignition
  • Sounds good, thank you for your time. I will try it tonight or tomorrow. I will post back results.

  • Re: Electronic ignition
  • I used a timing light to set mine.

    It would take two people if it isn't running.

    check this out.

    farmer dan, NAA manual says 0 degrees to install dist and 8 degrees at 450 rpms.

  • Re: Electronic ignition
  • Check the fly wheel. Some have 2 sets of timing marks
    180 deg apart. Make sure piston is on compression stroke.

  • Re: Electronic ignition
  • I could be wrong but it should be 4 B-TDC and I have never heard of an electronic ignition in 6 volts. I have only seen them in 12 volts.

  • Re: Electronic ignition
  • Both 6V and 12V Pertronix kits using the original Ignitor module are readily avauilable. IMO a better choice for side distributor tractors is the 12V only Ignitor II version. It's harder to find and a bit more expensive but won't self-destruct if you forget and leave the key on....

  • Re: Electronic ignition
  • I was not aware that Pertronix was doing anything 6v, good to know thanks. I like their Ignitor II wish thy made it for my motorcycle

  • Re: Electronic ignition
  • Yeah, me neither Dan, since I've never mucked with one B4. Pertronix webs site for Ignitor module says: 6-Volt NEG ground, and 6 & 12 volt positive ground modules available. SEE LINK below. As I have said in the past and will continue to state, most problems with 12-volt conversions are due to faulty/incorrect wiring issues. I don't totally oppose 12-volt conversions if done for the right reasons, and many are not, done simply because the original 6V/Positive Ground system has never been maintained properly, non-starting issues occur, and the 'solution' was to slap a 12-volt battery in place. I recently helped a fella with his '12-volt conversion' 8N and found he had a 12-volt battery connected positive ground; a 3-wire alternator wired incorrectly; a 12-volt car voltage regulator; and all wired to an automotive switch bypassing the safety neutral starter switch and with his lights tied in to it too. No wonder he couldn't start it. Oh, and I better also mention this setup was done by an 'old retired auto mechanic'. I guess it will never cease to amaze me the endless possibilities of hackmaster wiring setups.

  • I've got a 6V Pertronix on my '58 961 Dan and it works just fine.

  • Re: Electronic ignition
  • I should clarify, tractor is not running, gas to carb(checked with jar), spark will jump plug gapped quarter inch, good battery,new Dennis Carpenter wiring harness. I would like to see a 6 volt electric ignition diagram. Thanks

  • Re: Electronic ignition
  • Google is your friend, you will find what yo seek.
    With it not running did you set the flywheel to 8 degrees before installing the dist? If so try setting it to 0 degrees like the manual says.

  • Re: Electronic ignition
  • Can't find a wiring diagram on Google, all 12 volt. I will pull dist. and set flywheel to 0. Thanks for the idea, overlooked in manual.

  • Re: Electronic ignition
  • 6v modules & wiring are different for neg ground and positive ground. Next, "rotor pointing to #1", means physically to #1 cylinder or to #1 on distributor cap and is that distributor cap position actually wired to #1 cylinder? Are you doing this at TDC-compression stroke or TDC-exhaust......flywheel mark is same either way, but one will work & other win't.

  • Re: Electronic ignition
  • Positive ground. I mean pointing to the 1 plug wire and they are in the right spot1243. Top of compression stroke as far as I can feel it pushing air out of the plug hole. Thank you for your time

  • Re: Electronic ignition
  • 1-2-4-3 CW,, not CCW. Also, if you have good spark as mentioned, I would not worry about the EI wiring.

  • Re: Electronic ignition
  • JMOR do you how many times i.ve found that people wire a cap backwards they just start plugging in wires and can.t figure out why it backfires and won.t start I guess basic auto shop is not so basic anymore

  • Re: Electronic ignition
  • Might try number at TDC and rotor pointing to number 1. set to 8 degrees when running at 450 RPM.
