The tractor is wired for neg ground right ? A neg ground alternator connected to a pos ground system will produce exactly the damage you describe.
If battery is connected neg ground, it sounds like you had a dead short to the rectifier assy. Either a misplaced / broken / missing insulator on the BAT stud or a defective rectifier. The loose stator connection stud would indicate a bad rectifier assy.
The One wire conversion should have nothing to do with this, the problem was a shorted or improperly assembled rectifier and BAT stud, the exact same setup that is in a stock 3 wire system.
I have several farm rigs including a Steiger tractor and 1480 IH combine with one wire Delco 10SI conversions, none of them discharge a battery. Those machines are parked for 6 months without starting and battery discharge is not a problem.
I use a Self exciting regulator avalible from many companies for $7-10. They do not use any sort of resistor that would discharge the battery, only regulator circuitry that excites easily on the tiny bit of voltage induced by the residual magnetism in the rotor.
No need to use any goofy resistor or jury rig wiring when these regulators are avalible for so little cost.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
