8N generator wiring

Read some of the archives but did not find it. I just bought a 1950 8N and it looks like the seller had it converted to 12V but left the original generator on it. All three wires were running from the generator (G, F, and armature poles) to a voltage regulator right above the proof meter. But there wasn't anything running from the voltage regulator back to any other terminal anywhere. I quickly surmized that the battery is not getting any feed back from the generator. All the wiring was pitiful and in sorry shape so I pulled all wires off and rewired like the 12V conversion diagram says on www.n-series.com. It kept shorting out the system with the old generator wired in, I guess thats why he had it looped to the voltage regulator only. I've tried bypassing the generator altogether and I get nothing, not even the starter will turn over or lights will work. Hopefully I didn't fry something. Sparks were flying though.

Will old generators with the G,F, and armature poles work after converting to 12V? or Do I have to have a alternator with P1, P2 and Batt poles after converting to 12V?

Any help is greatfully appreciated.

A cheap 12V conversion is to put in a new coil and resistor, AND A 12v BATTERY....i'D BET THIS IS WHAT WAS DONE. cHARGING THE TRACTOR IS WITH A BATTERY CHARGER.

You may want to figure out what you have, and switch it back to 6V

But if it runs good on 12V, a one wire alternator would be great.

Good Luck
Steve.

Done figured out that he wired just enough to get it to start. It is a beautiful piece of art and I hate putting those ugly 12 volt alternators on them. They stick out like a wart on someones nose. I have to admit 12 volt is easier all around though. Jumping it off with the truck, lights are easier to find etc. Thanks

Another conversion done by a severely challanged person. Either put a 6 volt battery in, or install a 12 volt altinator or 12 volt generator/regulator. You need to take a look to see what he did with the coil if a 6 volt dropping resistor in series with the coil or installed a 12 volt coil..
Happy Motoring

Thanks Claus, I saw your name in the archives and started to request your expertise from the git go. Since my post I've already went down and picked up a 12volt alternator. There's no resistor on the old girl and the coil has been painted over. Whats the next best way to find out for sure he didn't need that resistor besides running it until the points fry?
