So I go out to work on it,, my 8N,, go to turn the ignition on and it's already on. I'm thinking battery dead? Nope turns right over but won't start.

I've obviously fried something. I'll go figure out what in a bit. I'm not sure when the key was turned on but it's probably been 3 or 4 days at least, longer if it was me that did the dirty deed.

It's a 12 volt system. My question is, is it possible to install parts that can't be fried when this happens? If so what are they and what are the consequences beyond a dead battery?

Thanks,

Roger

So, Turns out the coil primary was open. I yank the coil and it says use w/external resistor. I don't have a resistor. The conversion didn't come w/one.

I read the posts here on conversions and the only time I've seen a resistor mentioned is if a 6 volt coil is used.

The new coil autozone supplied doesn't say anything about a resistor.

Was the original kit incomplete or will I be OK?

Thanks,

Roger.

I just converted my 641 to 12V and the differance is like nite and day. Why I dicided to do it was after I jumped it off with 12 to the starter and it started quicker that it ever has. But to give the 6Vs its just due the previous owner had the coil wired backwards(it ran strong but hard starting) Also must have got some bleed back to the coil with the right polarity to help the starting when I jumped it. I also found a broke washer under the starter cable and the neg- battery cable was burnt up. Some my fault, but you dont want to tear apart a tractor that works for a living, which some of this might not of been found if not for the conversion. I put on cheap carbon core wires. I dont think the differance in resistance between the carbon and solid wires makes alot of differance since theyre both meant to do the same thing. I also put in a coil that was recommended in the archives by somebody which was a coil from a 67-later vw bug. It is an internal resistor and cost about $14 at autozone. I'll finish up sometime with the charging system. Right now the tractor starts as soon as the starter button makes contact with no choke. I like it.

You are getting the 12 to 6 volt dropping resistor mixed up with the ballast resistor. As I stated many times, most 12 volt coils need a ballast resistor. There are a few exceptions such as the new 12 volt coil from New Holland for the side mount and a few others. This has nothing to do with the kit.....

Correction:
The new New Holland Universal Coil uses an external resitor when used with 12 volts but no resistor when used in a 6 volt system.
Sorry for the error...

A friend of mine gave me a suggestion after he fried several coils on a 9N. Several times while using the 9N he stalled it, and just thought he would stop for the day, leaving the tractor where (and as) it stalled (ignition ON). When he came back, the coil was melted. So he thought of putting a beeper on the ignition switch. He got it at Radio Shack, one of those 12 volt 2 wire beepers that sounds like a backup warning beeper used on modern equipment. When the tractor was running he couldn't hear the beeper, when it stalled and the ignition was still on, the beep is there to remind you to turn of the ignition. I really should add this to my 8N, as one of my boys (2 yrs and 4 yrs) turned the ignition on. When needed to move the tractor, it had a dead battery (luckily only a dead battery).

I did something similar to one of my Harleys once. I bought a small horn,and wired it to the sending unit for the oil pressure with a switch wired in. After I started my Harley, I would turn the switch on, activating the system. The horn would sound if I lost oil pressure. I believe a system could be installed on the N like this, and the horn would only sound if the ignition was on and no oil pressure.---Michael

Usually, the first thing that "Cooks" is your coil and points. Is it possible to install parts that will not cook? Possible yes, probable no...
Good luck

Right after I got my 8N, some elf did the same thing to me (left the key on for a week). In my case I cooked the points which was a bear as the distributor is a front mount and I've got a pipe style loader wrapping around everything.

I though electronic ignition was fail safe for a key left on.

Yes they are, since they only pull current through the primary of the coil when the the distributor is turning. But where is anything stated that he has electronic ignition? I reread his post and see nothing in regard to electronic ignition. Did I miss the boat? I am allways a day late and a dollar short.

" My question is, is it possible to install parts that can't be fried when this happens? If so what are they and what are the consequences beyond a dead battery? " This is the part of his statement to which I made my comment.

There are currently no electronic ignitions for a front mount distributor to my knowledge. These of course will allow you to keep your ignition on without frying any parts. If you have a side mount you could spend the bucks to install electronic ignition.

Hi Everyone,

I do have the side mount distributor. I'll look into the electronic but for some reason I want to keep it the way it is (nostalgia???). I'll also check out the beeper and other ideas.

First thing I have to fix is the no ballast resistor situation. I have a small intermittent miss so I'll check out the points again. Seems there was a little grey on the contacts.

Then figure out why my new amp meter always shows 20 - 30. I'll take the battery out and charge it before I go snooping around.

Thanks,

Roger.

In regard to Electrinic converson kits for frount mount distribitors the here is a E-mail conservation with Genesee I resently had.

Dear Genesee,
I have a 1940 frount mount distribitor on a ford tractor 9N do you make a electrinic converson kit for it
Thank you

John
We don't offer bolt-in kit, but can provide parts for the brave few that have adapted standard components to fit the 9N. (Some machining required) Andy

thanks
how much does it cost and do you provide instrudctons or am I on my own

We provide basic instructions. Also there is an article in the Summer issue of the N-Newsletter on just such a conversion. Give us a call at 918-274-8000 for more details...I can talk much faster than I can type. Andy

That's what I thought. But hey, if you don't ask the answer is always no right?

Thanks Claus,
