Karl - What you describe can be done but it's got a couple drawbacks: 1 - The generator won't charge unless the engine RPM's are run up fairly high. Means if you spend a lot of time running slow or idling the battery won't charge. 2 - Heat! When you double the system voltage, the heat generated in generator field windings heat is quadrupled. Result is hot-running generator and shorter life. You CAN however keep a positive ground system with this approach - the generator doesn't care about ground polarity. (Most of the early 12 volt generator systems were positive ground anyway….) Now if your tractor is for work (not a show tractor), I recommend replacing the old generator with an alternator. A rebuilt alternator will cost about the same as a 12 volt generator regulator. And an alternator will be more reliable, and provides more charging current - especially at idle - than a generator & regulator system.
