ANSWER: Many original coils designed for use at 6 volts have a primary winding resistance as measured between their small + and - terminals around 1.25 to under 2 ohms (1.5 ohms typical)......THEY ARE LABELED 6 VOLTS
Thanks John, This is excactly what I was looking for.
There wasn't a battery on the tractor when I got it. I've basically been using my 12 volt lawn mower battery to hear it run. The wiring on the tractor is mostly original, missing its loom, and very ratty/broken up. The one and only battery cable that should have been connected from the starter button to the starter was only connected to the starter and was almost completly bare of its insulation.
The center post on the regulator is unhooked and I think thats the supposed to be the charging wire back to the amp meter.The wire was still there and hanging but has been disconnected from the amp meter as well. I tried connecting it to the terminals to see if anything would happen but I didnt get anything to register on the amp meter. May not be charging or it could be to much rust on the contact of the regulator. I havn't cleaned them yet.
The regulator is pretty rusty. I've seen where it has ink marking underneath the regulator that says 12v or 6v on aftermarket ones. I was wondering if IH put it on the OEM ones or not. I'll have to take a look at this.
Basically I would like to know what the charging system should be so that I can get a battery for it in the future. I figure I'll leave it the way it is, 12v or 6v, whatever it is.
I'm going to have to check out the generator for that tag today. Hopefully there is some paint left to it. It seems some one installed an upper mount off a car so that the alternator would swing further to tighten up the belt instead of tighting up the pulley. The hood hits against the mount and won't fully close.
Thanks for the wiring diagrams Jim, these will help and keep me from having to take other H part to see where the wires are supposed to run.

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
