Couple of things. Originally pos ground. With engine not running, turn switch on and observe ammeter. If it deflects to charge side , well you know it can't be charging when it isn't running so ammeter is hooked backwards for the ground that is on tractor at this time. If any lights work they will show easier on ammeter. Generators do not care which ground they operate at but need to be polarized to the one being used. The points in the regulator, years ago, were made out of different metals, positive being different from the neg point that is why the regulaltors were marked for what ground to use them with. For many years now, most all regulators are mfd to be used with eiether ground, (ever notice newer regulators do not last like they used to). Now, all that being said, a system like this with out any polarity sensitive diodes will function with reversed ground, if polarized, just that the ammeter will read opposite. Alternaters will not due to polarity sensitive diodes. By the voltage you are reading I am thinking you are not charging.

Today's Featured Article - History of the Nuffield Tractor: Conclusion - by Anthony West.

The two new models were given three figure numbers, instead of "three" and "four". Model numbers were introduced to help farmers and dealers instantly recognize the engine size and horsepower of the tractor, the 4/60 had a four cylinder diesel engine which developed 60 bhp at 2,000 rpm. The 3/42 had a 3 cylinder diesel engine which produced 42 bhp at 2,000 rpm. Th
