Thanks to all! A new tractor would never be this much fun!?!
Had the same problem with my 5000. Found a main harness plug up over the fuel tank had corroded and was pulling apart. Just had to clean it and put it back together the charging circuit then worked fine. I put a cable tie around the plug so it wouldn't come apart again.

Look in the service manual for your tractor.. you don't mention what model you have.. but if it's lucas.. I'm guessing 2000-3000-4000-5000 between 65 and 75.
I just rebuilt my lucas gen on my 5000.. at hi-idle I get about 14.1v.. and as high as 14.5 at pto rpm.
Use a analog volt meter.. the consumer grade digitals don't like the brush noise.
that unit is B-Circuit.. IE.. the field coil in the genny is grounded, and it expects field power controlled by the regulator.
Full field by jumping bat to field.. if that makes your battery votlage come up.. then the field circuit in the reg is bad.
If not, then bypass the cutout and jumper from armature to battery... see what you get.. you can also full field while doing this test.
CNH sells a new reg for this genny... .. the old lucas regs are prone to get dirty sticky contacts.
Polarize the genny by jumpering bat to field.
Motor test by slipping the belt off.. jump bat to field and bat to armature... if the genny spins.. it will likely charge... Most gennies that charge, will spin.. most gennies that spin, will charge.
