12 volt conversion ...nothing

have nothing when turn key and try push starter ...new everything from battery to solenoid....old starter turns when I bypass solenoid. Is there just 1 wire from solenoid to starter switch + battery cable solenoid to battery [ +..] I have 1947 2N
 
ahall.......yer scaring me, when ya say ya bypassed the solenoid. I even got out my MPC (master parts catalog) to refresh my re-memorys. The 3-speed 2N does NOT have a solenoid. That doesn't mean yer Billy-Bob corner parts replacer didn't install a solenoid, ...BUT... to ears used to the quiet speedy whirr of their BelchFire-V8, the slow rumpa-rumpa of yer 6-volt tractor starter kenn be disconcerting. I gitt that. Ennytime you have starting issues, replace yer sparkies...NO ARGUE!!! Recommend AutoLite 437's gapped 0.025. Don't throw yer sparkies away, just clean'n'dry 'em, one-atta-time in HOT running engine and sav'um fer the next time and there will be a NEXT time. Remember the drill; ignition ON, 1/3-throttle, 2 rumpa-rumpas on the starter motor and then a QUICK PULL on the spring-loaded choke, shuld gittcha started........HTH, Dell,yer self-appointed sparkie-meister
 
(quoted from post at 10:59:32 06/24/17) 2N's did not have a solenoid. They had a
mechanical starting switch. Did you add a
solenoid?

switched to 12 volt, added solenoid but tested starter by passing solenoid and it turned. engine ..new key on and press foot starter but nothing happens have new amp meter and 1 wire alternator , new points, condenser and 12 volt square coil ,new ignition key and resistor. thanks for help
 

i am curious - why did u change the starter setup? a 12 volt conversion requires no changes to that system. what are u calling a foot starter?
 
Well, you've got 3 responses and all 3 of us are totally in the dark about what you've done to the tractor.

Do you know the difference between a mechanical start switch and solenoid?

On an 8N, when you press the starter button on the top of the transmission, it electrically closes the solenoid on top of the starter which then allows battery voltage to go to the starter.

On a 2N, the large starter switch below the steering wheel in front of the transmission cover mechanically (not electrically) pushes a piece of linkage into a starter switch on the front of the steering column that allows the battery voltage to flow to the starter.

If you have a solenoid, you must have an electrical method of activating it. And the thumb switch on a 2N will not do that.

So, tell us what you have and exactly how you wired it.

did not know about the mechanical switch until today and wired tractor as one would wire 8n conversion. With my thanks and new knowledge I will take away solenoid and wire the starter to mechanical switch and up to battery. I had a wire going from solenoid up to ammeter. Would I bring it up to ammeter from other terminal of starter switch which has battery cable ? Should I add another resistor to 12 volt coil wire [ coil was 3.5 ohms ] ?
 
ahall.........NO MORE RESISTORS. yer 12-volt coil is already 12-volts. Ya adda resistor, you'll turn yer 12-volt coil to WEAK 6-volt coil and WEAK sparkies. DONNA DUE ITT!!!.......Dell, yer amazed sparkie-meister
 
Do NOT add another resistor as Dell said.
You have a 12v coil. All you need is the oem
ballast resistor. ( see tip # 30) Google
"wiring diagrams JMOR" and find the one that
fits your tractor.

First time posting here, I think this is a good place to start.

My 6volt 8n tractor battery is dead and I was getting ready to buy a Electronic Ignition.

Hmm, time for 12 volts?

I'm ready to do it but I don't want an Alternator. Why? Because it just don't seem right. For a working tractor it might be okay, and makes good sense. But my tractor is not really a working tractor. I have two other tractors for real work and the 8N is 2nd string backup.

Went to a antique tractor show this early May and saw a nice 8N, but with a chrome alternator. Have they no shame?

It seems like the 8N parts resellers can only sell me a Alternator. I see Hot Rod alternators that look like generators, but they are big bucks, ~$400.

I see places that state just putting in a 12volt regulator can do the trick, but the result is not a high output gennie.
That may be okay.

I also have a Model T Ford, this group has same desire to go to 12 volts but they have a hood that hides an alternator. I found this product, that I might try. https://www.modeltford.com/item/T12CK.aspx/

The generator rewind/modification option sounds like the best option. But it's the 4th of July and I need to wait another day to start price checking.

I love to be able to jump the 8N with my wifes car, or any modern car. So 8 volts is out.
I want the Electronic ignition, you can't see it, so it's okay. But before I buy it I need to solve my 12 volt GENERATOR problem.

Does anybody know of a vendor that offers a 12 volt 8N generator? I would pay more for it then an alternator solution.

Well no, actually it's not. You're hijacking a thread. Next time, click on " Post a Message" at th top left.

But means you're here.............

" My 6volt 8n tractor battery is dead and I was getting ready to buy a Electronic Ignition. Hmm, time for 12 volts?"

Those questions have been asked & answered 100 times here, so do an archives search.

" I love to be able to jump the 8N with my wifes car, or any modern car. "

That's easy; see tip # 43 at the link.

If you want 12 volts out of a generator, buy a 12 volt generator. Plenty of them out there. Or take your 6v generator to the shop & have it converted.

But the question you need to ask.....and only you can answer it.....is: what do I want out of this tractor?

I've got 3 8N's all restored to look just like Henry made them. All are 6 volts, all have points & all run perfectly. IF you want to do that and IF you want to do the maintenance on them ( see tip # 40) then your tractor will run just fine on 6 volts and points. Your tractor, your wallet, therefore, your call.

BTW, I also have a 1929 Ford. And it looks like 1929 Ford. But it has a 6 volt positive ground alternator and V-8 Ford points.

I had the generator on my 8N rebuilt and converted to 12V by a local shop. New field coils but no armature rewind. Total cost with new regulator was a biscuit over $200.
