9n Wiring

Hello, I've looked at all the wiring diagrams, nothing makes sense to me as apparantly, got a goofy looking drawing I made up, hope it makes sense to someone, I'd love it if someone could direct where A-F wires go to, say A goes to 3 and so on. Sorry ahead of time if this is a waste of time. Thanks

Good grief, I'll figure this out eventually, it will not let me attach a picture to email you, I'll try to go through hotmail or something

If you Google JMOR Wiring Diagrams you will get the whole story on correct wiring for just about any config out there. We also have them available on 'the other ford tractor site' -email me for the web site as the admins here don't want anyone to know about us and therefore won't allow us to link or even post their name. DUH! It's a about sharing information and helping out folks just like you.

Now, though you say you have a 9N, it all hinges on what model year and how the electrical is set up. The early 9Ns used a small generator, two-wire/two-brush type, rare, but also used a square voltage regulator, unique to only the early 9Ns. Shortly after -late '39/early '40 the gen got changed to a one-wire/three brush type that then used the round-can cutout. Shortly after that the gen went thru a few more changes but the cutout remained until the 8N model. We need a bit more info on what your set up is like too. Is it the 6-volt positive ground as was the original config, or a 12-volt w/alternator conversion?

Alrighty thanks, I got my picture emailed to him, he seemed pretty confused haha, I've got the hood off and all that so I can take some good pictures of what's all going on.
I believe it is 6 volt positive ground. Any idea why it will not let me add pictures to the site here?

You have to get a few posts under your belt before you are allowed to post pictures , keep posting and trying to post pictures. You will get there.

"I got my picture emailed to him, he seemed pretty confused"

The picture may be confusing but if anyone can help you,
you've got the right guy!

Hello; I had the same problems with my tractor. Had to rebuild the generator - a three wire kind... Gnd, Field, Arm (works fine now -cost $40.00), but when I put everything back together It wasn't charging. The Regulator is marked B-A-F... It has a Yellow wire going to the B terminal, a Red wire to the A terminal, and the White wire to the F terminal.
I could not find any diagram showing a Red wire! But I took the Regulator off and found stuck contacts on the small relay... cleaned all the contacts in the regulator and re-installed it. Started the tractor - still no charging... until I momentary jumped the B & A terminals on the regulator! Everything now works! There were so many wiring harness changes that the colors don't seem to make any sense! And instructions on "Flashing" the Generator Field vary - but this worked for me. Hope this will help to get your problems solved!

There are a few things you do not seem to
understand.

The reason that the instructions on
polarizing the generator vary is because the
type of generator circuit determines how
it's polarized. ( see tip 23) If you do it
wrong, you can easily burn up a v/r. Before
you suggest that someone take your advice,
you should state what model tractor you
have. What worked for you could result in
the other guy burning up his v/r.

And the color of the wires is not relevant.
The armature wire from the generator goes to
the armature terminal on the v/r, etc, etc.
If it's red, green or purple, it does not
matter. If you have a red wire attached to
your generator armature, then attach the
other end of that same red wire to the
armature post on the v/,.

This isn't rocket science. Don't over-think
it.
