Installed 12 volt conversion kit,including wiring harness.Everything works but not charging.Any clues to my problem would be appreciated!
Thanks,
Pete

When you say 'everything works but no charge', I'll assume? that the ignition is fine, and the tractor starts and runs.. just no charg is showing on the ammeter.

First.. do you know the ammeter is good? Easy to test by removing it, and putting it inline with a load.. like a tractor light, and hook up to the battery.. it should show the amperage the light is drawing.

You did switch to negative ground right?

Also.. if a side mount coil, did you switch the polarity on the coil?

Let us know.

Pete..... ..ya didn't give us enuff clues to even begin to help ya. Gotta realize theres 2 different kinds of ignition systems, squarecan 4-nipple frontmount, and roundcan 5-nipple sidemount. Then there are 2 kinds of ignition coils, the cheap way with a 12 to 6 volt converting resistor plus the original 6 volt coil, and the better way using a real 12 volt coil. Then there's the deceptively desireable 1-wire alternator that starts charging at 1800 rpms ...OR... the 3-wire General Motors way that starts charging at 600 rpms.

So you see, there's 6 possible answers. I flunked mind reading, just ask my ex-wife..... ....Dell

Do all 1 wire alternators begin charging at 1800 rpms? If so, I'm cancelling my plans to install one on my '67 CJ5 Jeep.

I was under the apparent false impression that all alternators charge at idle.

Herb..... ...as a general rule, the 1-wire 12 volt alternator conversion works just fine in automotive applications. Most people bring their automotive engine upto 3000 rpms to start moving the vehicle with eather clutch or automatic tranny. Once the 1-wire alternator "self-excites" it'll charge at idle.

The N-Engine idle spec is a sloooowww 400 rpms and max rpms is 2200. I just don't like jazzing a cold engine to 1800 rpms just to get the self-excited alternator to start charging.

Bottom line, I wouldn't have heartburn over a 1-wire 12 volt alternator conversion in a Jeep. Remember to use a "real 12 volt coil" and NO RESISTORS for maximum sparkies..... ..Dell

Pulley makes a big difference, as well as if it can be excited externally , and how it is excited, if external...

Dell and Soundguy, I don't know if you guys are aware of this, but if your having your alternators made up by a local rebuilder they have a new regulator out for the delco 10si's that usually brings the turn on speed down to the r.p.m. that a stock alternator kicks in at if not lower. It is transpo #d10ac. It makes a huge diffrence in turn on speed.

jstpa..... ...I don't do conversions 'cuz I ain't found a good enuff reason to convert my eazy startin' 6 volt '52 8N. I just know 7-ways to do it right the first time.

I'm aware of a lower rpm turn-on 1-wire conversion module for the popular Delco 10SI alternator. Its never gonna be as low rpm turn-on as the 3-wire "switched excite" OEM Delco module..... ....respectfully, Dell

Dell,
I just wanted to let you guys know that there was a diffrent route for the one wires.And respectfully, When you run a stock alternator on a test bench the alternator turn on is usually between 1200 and 1500 rpms, the regulator I'm talking about will turn on most of them in the same rpm range. I've even had them turn on at a 1000 or so rpms.Just food for thought if anybody is considering the change.Personally I'm like you Dell, I don't see a reason to change my naa over either.

So far I'm lucky. I havn't had to put up with much vodo from the electrical systems on my tractors.
My 8n is oem 6v pos grnd.. Just had to get a new reg for it when I got the tractor...previous owner knew wood working.. not tractor wireing... had an 8v battery in it too...got rid of that fast.. My NAA has an older 3 wire delco alternator on it.. but it uses a voltage regulator, and charges fine... kicks in at 6-700 rpm..
My 2n also has a delco alternator on it ( unknown type.. but older. ).. has an exciter switch, but I've found that it takes off on it own at about 1/3rd throttle or less sometimes..... I'm guessing 7-800 rpm?.. has a real small pulley.

My IH cub has an oem 12v genny.. works decent.. had some bad wireing but was easy to clean up. And my JD-B has an oem 6v genny.. which was disconnected and had been for some time when i got it.. I hooked it back up and off it went.. still happily charging..

Do you have any time to use all those tractors? It must be fun to be young again! I'm retired and hardly have time to keep my one and only tractor, "8N" in condition. Probably because my son keeps me working it on his property morning till night.

They take turns working... or playing. The JD pretty much just drives around the neighborhood and gets waved at.. not much work for it. It is heavier than even my NH 1920, and I have a feeling that it -may- print on the pasture, due to the narroe tires, high weight, and trike stance.

But like I said.. the others take turns on the pasture chores.. spreading seed / fertalizer, pushing up the maneuer pile, dragging the pasture, and mowing, and once a week driving the fence line to check for holes ( occasional gopher / dog ) and loose boards.

I think I've um.. greatly exceded my 'justifiable' tractor allotment. I think 3 would have been a good 'theoretical maxumum'.. 1 to work.. one to help with boom pole, etc.. and one as a backup or to leave hooked up to an implement.. etc.. Oh well.. I wonder if there is a penality for to many? ;->

I used a one wire Gm alt,I didnt realize it doesnt charge till 1800 rpms.I used a 12 volt coil also.As far as 4 or 5 nipple mount,you have lost me.can you help me,
Thanks,

He means the style of the engine, which is also determined by the year. The 4 nipple square is slang for the front mount distributor, and the 5 nipple round can is slang for the side mount distributor.
