Will the later model voltage regulator, the one with the three terminals on the bottom side, replace the earlier voltage regulator with the terminals on the top and side? The parts manual list them both as 8N10505-C. I have the earlier 8N with the front mount distributor.( s/n 8N189414)Also, the parts manual shows the generator is different between the earlier (8N10000-B) and the later (8N10001) models.

If the generator that you are using has 3 terminals @ Gen Fld grnd, then the later regulator will work.
If the generator has only one outlet it will take a cutout instead of a voltage regulator.
Also the automotive regulators of similar years will work.The mounting is different and the automotive regulators have 3 sections instead of the two that the tractor regulators have.The 3rd section in the automotive regulator is a current regulator which the tractor regulators do not have because tractors do not need because of a much less current demand.

I have a 49 8n,& I just went through a similar experience. My generator is a two brush generator with a GRND, ARM,& FLD, post. Make certain that your replacement voltage regulator with terminals on the bottom, has the battery terminal on the left side while looking at cap side (blue etc) up
and terminals facing down. Good luck.
