I am going to convert my 52 8n to 12 volts before this spring so I can run my sprayer and help with a couple of other duties (jumping dead batteries). I want to stay as original as possible. Can't I just take my generator down and have it converted to 12 volts and change out the regulator? If not why? This would be cheaper more practical and I would not be as likely to have the problems people always report. Right?

Thanks for any input,
Ron

Ps, I know, new battery, lights.....

Ron..... ....there is no reason why you can't have a 6 volt N-Generator converted to 12 volts by a competent generator shop. Ya juss gotta find one (grin).

Gotta 'nuther take on this one tho. There were real 12 volt generators made that might be a better (less expensive) deal. Try 60's Ford Falcons fer example with matching voltage regulator. Alternators didn't become common until mid-60's.

Watch yer pulleys. Need a 5/8 pulley on generator to match yer N's pulley belt water pump and crankshaft..... ...Dell

Like Dell says, Find a good competent shop to convert it; OR: Ford converted most of its line to 12V in 1956. Alternators were not the norm for the industry so Ford, as did others, stayed with generators. Find a Ford generator from between the years of 1956 through 1963 and the generator and regulator will work. Ford introduced the alternator on the T-bird in 1963.

Dell.....your a man after my own heart. I have a 64 Falcon vertible. That's what gave me the idea. I have a couple of old generators layin around that I know work but I could not get the brackets and case to come together like it should.

Thanks all for the input...we are off to the local alternator shop.

HAPPY NEW YEAR!

You never hear from the 12V upgrades that WORK.

You only see posts when something goes wrong. But there are tens of thousands of 12V upgrades out there that are working just fine. It's only when they are done wrong that something goes wrong. I got mine from Genesee Products (they have adds on this board) and it was easy, and I have had no electrical problems at all. And it has an alternator and Solid State regulator. If it were mine, I'd save the old 6 volt generator and harness, and that crappy Buzz Box, in case I ever wanted to go back. (You won't). Then, I'd buy a commercial 12 volt kit, follow the instructions, and then gaze in Wide Wonder at the 12 Volt juice available from your N Tractor. You'll be able to run DVD's, Coffee makers, Short Wave Radios, Lap Tops, Internet Routers, Radar Detectors, Cell Phones (hands free in NY State) all can be powered with 12 Volts, while riding along on your tractor. Heated seats. Electric shavers. CD Burners. You'll wonder how you managed without all of this stuff. The possibilities are endless....
Just my opinion.

Tens of thousands? I doubt it. I have yet to see a tractor at a sale with a good-looking 12-volt conversion. They usually have a spaghetti-bundle of wires hanginging out with big gobs of electrical tape and quick-splices.

You never hear from the ones that work because:
1. They don't work
2. If they do, nobody wants anybody else to know that the God of Fortune has smiled upon them for once.

i was going over some posts and saw this one. i wish i could show you my 12v conversion. when i rebuilt my 47 i did the conversion right. it looks good and performs well. i got my alternator from a local shop and they set it so it would start charging around 800 rpms which it does unless i havent run it for a couple weeks then i have to rev it to around 1200 to kick in. i'm an aircraft mech for a living and cannot stand to jerry rig anything. i even made a alt bracket that looks like it came off a car, curved not straight. anyway, there is at least one 12v conv that is done right.

How many Automobiles built today have Generators?

Why do you think there are no Automobiles built today with generators?

I rewired a '41 Ford coupe to use a 12 volt system by winding the generator to 12 volts, starter to 12 volts, changing the regulator to 12 volts. Retained postitve ground system. Used two Optima 6 volt batteries in series. Retained 6 volts for ignition, radio, gauges, etc., and 12 volts for lights, starter, etc. Looks totally stock, but has all the starting advantages of 12 volts, plus better lights. The wiring harness is totally original style and I only had to add one wire for the conversion! Your comment about why no modern cars use a generator.....You are comparing apples to oranges. Modern cars have infinitely more electronic gadgets to power than do older cars and all tractors. Alternators, in my humble opinion, are overkill. Although alternators put out more current than a generator, a generator, in good condition, will fill the demands of any tractor, especially an N series Ford. A 540 cid engine works well in your pulling tractor, but do you want one on your 21 inch push mower? Same scenario applies to alternators on tractors. If the engineers who built it thought that your 8N needed an alternator, they could have invented one for it, just like they did the tractor. My two cents..... ..Regards, P

Why didn't you read my post? I don't care about autos I care about my tractor looking as original as possible yet get 12 volts.

I doubt if you are going to save any money by changing over your generator to 12Volt. The reason I went to 12Volt was to get away from a generator and cutout Voltage regulator.
Unless you go to an alternator you will still have the problems inherent in the generator and cutout voltage regulator setup.
I started from scratch, not knowing anything, did not have the resources of this forum, and with a little advise from a guy at Shelby Generator was able to get and install an Alternator that has never given me a problem in the 6 years + that I have been running it. I also have never had to replace the battery yet or even get a jumpstart for it but after 6/7 years it must be ready for replacement.
So not all installations are troublesome. The ones who have trouble have inadvertently misinterpreted the instructions somehow (which we all do occasionaly) and that is why they need assistance.
IMHO

I would follow BGs advice, but you'll need to check the field wiring of the new generator. Your stock generator switches the 'ground' side of the field coil (this is called 'A' circuit, common to Delco-Remy stuff), and most of the newer 1953-up ford generators are 'B' circuit (switches the 'hot' side of the field). You CAN get a 12V armature to fit your generator case. If you go to a local rebuilder, you might get a hint more expertise on the subject.

Any competent auto electric shop ought to be able to do what you propose.

You will still need to get correct coil voltage which is where about half of twelve volt conversions go bad. No rocket science here but for some reason there are lots of folks that don't get it on the first, or second try.

Your mileage may vary

You can buy a new 12 volt DC, 22 amp Ford generator from Surplus Center for $99.50. I'd do that so you could change it back if needed. Buy a 12-volt coil and VR at NAPA.

Don't be fooled, there are lots of us with 'converted' Fords out here running our 12 volt systems with no ill effects whatsoever. No doubt you've seen a few tractors that look as if an orangutan had wired them.

If you understand basic electricity and can follow simple schematics you'll be fine. You can draw you OWN schematic or diagram. if you like.

If you don't like electricity, hire it done... by someone who does.
