I connected my multi-meter and set it on ohm's. I turned the distributor til the points closed...touched the leads from the meter to the breaker point spring of the points, and the other to the housing. It zeroed out (to less than negative movement...off left side of ohm scale). I then opened the points, and connected ohm meter in same fashion. No movement at all on the ohm scale. According to Nseries.com this means the distributor is shorting out somewhwere. I took it apart, checked for bad insulators of the springs assembly, and points...all seems fine and clean. Points appear to be ok too and checked the gap... .015...ok. I re-set the timing per instructions, but it was fine initially. Any suggestions what to do next? Purchase a new distributor? expensive item! or check condensor? 9n'er

AS CLAUS SAID YOUR OHMMETER CHECK SAYS YOUR POINTS ARE OK. DO THE VOLTAGE CHECK LIKE CLAUS RECOMMENDED. I FORGOT WHAT KIND OF COIL YOU HAVE. YOU SHOULD SEE 3.5 VOLTS IF YOU HAVE THE SIX VOLT COIL. STICK WITH YOUR 12V FOR NOW. CHANGING TO SIX VOLTS ISNT GOING TO FIX YOUR PROBLEM. I THINK THE BEST THING YOU CAN DO FOR AN OLD N IS GIVE IT 12V. GOOD LUCK

9n'er,
Like a lot of other people, I've been following your exploits over the last few months and in my case anyway, it's like waiting to see how a good movie is going to end.
Maybe, just maybe, it might be time to make friends with one of your local mechanics. (A 12 pack can go a long way.) It sounds like you're real close to firing it up. After all, it ran before you tore it down, so the chances of something failing in the interim seems remote. Keep us posted and I wish I was there to see the look on your face when it finally lights up. (The tractor.)
Good Luck,
Chuck

Last night on the way home I stopped at the local garage, and offered to put the mechanic up for a few days, and feed him too (I just have a feeling I cannot trace this ailment...despite my eforts). I scheduled a visit for Tuesday. Told him the problem, he shrugged, and said ok, in low key manner. I hated to do it, but I just don't have the time to fiddle with it anymore; been putting off other stuff to figure this out; but I've reached the "Law of Diminishing Returns." Enough is enough. Will fiddle with it today; and then that's it. Visited a local tractor mechanic this morning before work (local meaning 1 hour plus away). He said 90% of the problems regarding no spark to the plugs has to do with the points going bad, or just not right...he said it doesn't take much for them to not function...even a slight film on them...he sold me points and a condensor. I looked at the old points and they are worn. I plan on replacing the ballast resistor too. If that doesn't do it...well, I'll pay the mechanic. We're on the same frequency...can't agree with you more. thanks. -9N'er.

When the meter goes to zero, that means that you have continuity which is corrent when the points are closed. When the points are open you should not get a reading on the meter (No movement of the needle...) It looks like there is nothing wrong with your distributor..

Ok, since you have an analog meter, check the connection on top of the coil, (Place meter in the voltage position) and see if you can read 3.5 volts or so when the points are closed and 6 volts when the points are open. Jog the engine with the starter with the ignition off to do this.
Happy Motoring
