Just purchased a jd 620 missing generator, pre owner had started to install a alternator. looking for wiring diagram on how to wire alt for negative ground tractor.
These tractors were 12 volt positive ground. They originally used two 6 volt batteries wired in series, instead of one 12 volt battery. Why not just put a generator back on it? Makes it look better and the technology is sound as there are plenty of them out there still with generators today.
