9N 12V conversion

So I want to convert my '39 to a 12 volt system. The description on the kit for sale here says "for 8N 9N 2N 1942 to 1951" etc etc. I'm thinking it's just funny wording that's tripping me up but want to be sure. Will this kit work on my '39? Thanks for any help!

Can't say that I've ever converted a '39.
I'd like to find a '39. Closest I've found reasonable is a '41.
But some pieces will work, alternator, etc. If your tractor is
really a '39 the wiring will be different because of the starter
button and key switch placement, engine running light, etc.
Probably cheaper to roll your own conversion kit in that case.
Others like HCooke will have first hand knowledge on the '39s.

Pretty sure it's a '39. S/N ⭐️9N2665⭐️?

Serial number would say so. Parts do get changed though.
Check out John Smith's great site for more ID info.

Pretty sure it's fairly original besides a recent engine overhaul. Got it off a coworker who inherited it when he bought the old farm from his Grandmother inlaw. Really happy with the old girl so far!

Lots of good info on that page! Definitely a bunch of mix match parts on my tractor!

tbomber.......maybe, maybe not on yer '39. Heres the deal, Ford made some dashboard changes to the electrical wiring. Nuttn' a good mechanic can't figger out. ...but... Ford did standardize the 9N/2N/8N 4-nipple front mount dizzy after '42 production control board released controls on rubber (ag-bar tires 'stedda tank treads) copper (radiators 'stedda bullets) lead (batterys 'stedda bullets) Early WW2 2N's had magnetos and arm-strong starters (hand crank) witha radiator mounted choke knob. That only lasted fer about 6-mos. In late '51, Ford changed to the 5-nipple side mount. You can count nipples can't you?

I'ma 12-volt advocate for the right reasons. A new rebuilt N-Engine should start right up on 6-volt battery. Unfortunately, our ears are so used to the quiet whirr of yer BelchFire-V8 starter that the SLOOoow rumpa-rumpa of yer 6-volt starter makes you think sumptin' is wrong and you need to convert to 12-volts. Granted, 12-volts on yer original 6-volt starter motor will really maker whirl. Kinda handy on low compression worn-out N-Engine. BTW intermittent 12V on yer 6V starter motor does NOT hurt it.

Remember, onna 12-v conversion, you STILL need the "infamous" ballast resistor. And depending upon the kit, you will gitta 12-to-6 volt converting resistor too. We recommend the MODERN 12-volt squarecan top terminal ignition coil that uses NO 12-volt converting resistor but still requires the MANDATORY ballast resistor. Unfortunately there is NO eazy way to tell the difference between the original 6-volt coil and the modern 12-volt coil. (except by label on the box) .........HTH, 12-volt Dell

I have 4 39s. Two of them were 12 volt when I got
them. I kept one that way. Conversion works the
same way as on any N. Some of the wiring may be a
little different. Example - neg cable on a 39 is
short and goes to a starter button on the dash
instead of a stater switch below the battery. Key
ignition is on the right side of the dash so the
wiring form that will be a little longer.
Everything else is the same. You can roll your own
or start with the kit sold here at YT and adapt.

Thanks for all the help so far! I've got single rib fenders, riveted rear axles, starter button at the shifter, solid left lifter, fat generator, and no freeze plug. All of that, and rear axle housings with 2N 4015 A2, 3-19-46 (left side) and 2N 4014 A2, 12-21-45 (right) in the castings leads me to think I've got an early '46 2N with a later '39 9N engine block. Sound right to ya'll?

Starting isn't an issue. A little lazy like you say but she always fires right up... Unless i go full retard and flood it... I'm Really just looking to make it more conducive to my life. Everything is 12V, if I'm on the old Ford and my wife yells "I left my headlights on again!" I can just pull up and jump her... Her car that is...Plus I'd like to mount my plow on the front and use her to push snow and things like that. As far as nipples go, I count 4... on the tractor... As far as the kit is concerned i'm just hoping for everything to bolt up. I'm an electrician/controls Tech by trade, so cipherin some wyrin shouldn't be an issue. And I can fabricated, but a wife, 2 kids, a 50ish hour a week job, and a bevy of other hobbies has me liking the sounds of a bolt on deal.

Sounds about right to me. On the bright side, that means
the 12V conversion kit should pretty much bolt right on.

Yes, and in that case a standard 9/2N 12 volt kit
will be plug and play.

Mutts are good.

"Mutts are good."

Agreed! Many parts interchange and swapping an original
part from a similar year/model tractor will probably net a
better quality part than I can buy aftermarket.
