I had it tested the field was shot in the SG, Also the end with the bearing is worn out and had to order a new one of those as well. . . It would idle all day long (exaggeration lol) but at higher RPM's it would rapidly drain the battery checking the voltage on the battery. . . Idling it would just tick down . . If that makes any sense . . . But it was confirmed today by the man that tested it, he is going to test my regulator too just to make sure it isn't burned up from the SG being messed up. . .
Hopefully it will be a easy rebuild so you can enjoy the awesome tractor that they are. Like I said I'm not to familiar with SG I have one on my Monty . Haven't had it very long no problems with it . All my Case Ingersols are stator's. So good luck on fix.
