I have an 8N that I purchased last December. I just had the engine rebuilt, plus carb, brakes, etc. The only real question left is to convert to a 12 volt system?

There must be pros and cons, but I am not sure which way to go...at this time I think it's a good thing to do...the mechanic does too...but I was hoping to get some feed back from the folks around here first.

The tractor will be used for snow plowing, brush hog, trailering..

Thanks for your thoughts and advice.

Thank you all for your input.

Since this tractor is a working tractor (2-4 days each week), and since it's at the shop now...I have decided to go with the 12v set up.

Of course I will save the 6v items since I never throw out anything, thankfully I have a barn to put my "collections" in.

Overall I think I am making out well on the conversion, I have a new starter and battery that were given to me at no charge and we have all the wiring required...since the hood/shroud are off and it's being redone at this time it seems like a good thing to do. Besides there are some items I would like to run off the 12 v system.

I appologize to the purists out there...I inherited my fathers 8N last year and it is still a 6v system...so I am keeping one the way it is for now.

Again, thank you for your input and advice. I am sure as I learn more about the N's I will have many conversations on this topic...sounds like an interesting way to share a cup of coffee.

I just converted my 44 2N to 12 volts. I would have kept it 6v but the generator didn't work. I took it for a rebuild and the insides were fried and the brush holders were gone. It was much cheaper to convert than buy a new generator. I followed the diagrams here on the board and had no trouble. The hardest part was getting the 2 head bolts off to mount the alternator bracket.

I'm no lover of the 6 volt, but it works fine if set up right. It requires (emphasise requires) clean connections and heavy cables. With that, it'll work just fine day in and day out, for years on end. Let a connection corrode just a little bit, and you'll have a tractor that cranks over slow and is hard to start.

12 volt has the major benefit of being less maintenance intensive and better able to hook up to components. Depending on what you do, this can be important, or negligible.

Myself, I'm still running my 6v generator, but that's only because I haven't purchased any 12 volt accessories that I need to run. If I do, a 12 volt alternator will go on the tractor.

Why spend the money if you don't need to I am not really a purist mine, is a workig tractor used for the same as yours plus landscaping. It is a six volt system and works just fine. I notice that the 12v devotees like to make out like the 6 v is unreliable and maintenence intensive. I am no expert mechanic but I have had no trouble with 6 volts starts every time no matter the weather. IMHO save the money until you need to do a repair on the system then convert

I've never voiced my opinion on the 6 vs 12 volt thing, but, today, I'm a gonna. To me, it's just like the water in the oil thing. They don't get used enough to drive the water out. Same way with the electrical system. This system was designed to be used hard and long and it worked. But, you say, I use mine every day. Lets tear that apart; Say you got your little wagon behind the tractor and you're planting your white pine trees. You dig a hole and put the tree in it and fill in around it. Then you start your tractor and pull up ten feet and do it all over again. You have 35 trees to plant. You work till dark and then (because you can) you turn the lights on (cool) and head for the barn. After a period of time using your tractor like this, you start having problems. It won't start, the battery died. Damned old 6 volt system, that battery wasn't even two years old. Why did this happen? Get out your FO-4 and follow along. It says that each hot start requires 100 to 150 amps. The electrified guys, (Dell and Claus) tell us that the coil requires about 3 amps to keep the engine running. If I'm not mistaken, each light requires 5 amps. All this from a generator that in new condition puts out about 11.5 amps and it does this at around 1000 to 1500 rpm, not at slightly above idle. (shes an old tractor, I'm gonna take real good care of her and not run her hard) Well, are you starting to see where I'm coming from? You ruined the battery by shutting it off in the down condition and it started it's process called sulfiding (deterioration). How do we get around this demon? We start by buying our new 6 volt battery made specifically for a tractor. (Yes, there is a difference, they are built heavier than a car battery.) Then, use the tractor in your usual manner and when you pull it into the barn-hook up a trickle charger to it and all will be well. The reason you don't hear the fellows with 12 volt alternator systems complaining about this is; An alternator can put out 40, 50, even 60 amps and it can even charge some at an idle, (not so with a generator.) So, it boils down to this-if you use your tractor lightly, help out it's electrical system by putting the charger on it when you are done with it. ( we already know to keep everything bright and shiny and tight and to keep the water level above the plates in the battery.) Or, go to the alternator system and eliminate it. The choice is yours, it's 6 of one and 12 of the other. L8R----Fred OH

you will get (about) 430 postings regarding this topic.

Generally, it seems to be a religious war
whether you should convert to 12v.

Pros: 12v alternators provide reliable power at a higher voltage that appeals to some, and usually makes winter starting easier.

Cons: 6v system will work if properly maintained, and it is "original". Cost money to do.

Happy reading.

If you do convert - save all the 6V pieces - someone may want them & they don't take up much room. I would suggest you buy one of the kits available from the people that support this board. These kits should not require you to alter anything structurally on the tractor. I have one on my tractor & no longer have any starting problems but I'm too lazy/busy to keep the maintenance up on the 6V system that was there.

Bill- Good reply!

Sal- Go figger... do you want a museum piece, or a machine you can use, reliably, in day to day activites?

I had to do starter repairs on my 8N at least once each winter. In the early 70's I converted to 12 volts. After that I never had to mess with the starter. Touch the button and it was running, instead of all the grinding and chewing up mechanical parts.

Like Bill sez, there's a purist element that is against 12 volts. Let 'em have museum pieces and build you a machine that'll keep running well into this century long after it was designed, built, and sold!

Your question boils down to- Do you wanna stand around looking at it, or do you wanna use it in your day to day activity?

Keep on truckin', IHank

Hank and Bill, I concur. I am a 12 volt advocate for the right reasons. And for you, your reasons are "right".

Sal..... .If you want to convert to 12 volts for what ever reason, just do it "right" so that you are proud of it. If you follow the instructions that come with a "kit", you'll probably do fine. If you don't understand the instructions, ask questions, don't guess. And remember 2 wrongs don't make a wright. (grin)

FYI..... my eazy starting 52 8N is still 6 volts and I know how to convert to 12 volts the "right" way and the electrical reasons why. I'm not a "purest", just haven't found "my reason". I wish you well..... ..Dell

I have an 8N and have thought about going to 12 volts. I have purchased all the necessary parts to go to 12 volts and I still haven't done it.
My experience with my N is that any starting problems(really minimal)that I have had wouldn't go away with a 12 volt conversion. If your connections are dirty it doesn't matter how fast your starter goes around!!!!!
