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.

Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. 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.
