I picked up an 8 hp Wisconsin engine, along with a bunch of other items Friday.  Owner said the starter/generator went out and he could not find another 6 Volts unit.  This is an 850 he is talking about.  I had another 850 pars tractor and it had a 12  Volt Start/Gen on it.  I also have some extra regulators and relays on hand from Bolens units.


How does one tell if a regulator is 6 Volt or 12 volt?  Mine have no marking on them at all.  Only the 3 terminals are marked.  I believe they all came from Wisconsin engine set ups but not positive.

I'm not aware of any garden tractor using a 6 volt starter generator, unless it was something very odd and very early.  Come to think of it, I don't know if they even made that technology until the late 1950's, and that was 12 volt time by then.

Some tractors were 6v up to the mid 1950s and VW was 6v up to 1966(?). Other than those, everything that I've worked on was 12v or 24v(Dozer and Army). Someone was probably just mistaken. The generator should have a data tag with the voltage and amperage. Good Luck, Rick

Think Delco Remy, most popular just had diff color tags is all with a model number. Seems like Red for one and Blue for other, but not sure which was which. Many times the model numbers which are quite long are worn off or even the whole tags are gone or painted over. Also believe the outer feilds are what makes them diff, not the armatures.

Thanks a lot guys. You confirmed what I was thinking all along. I wonder if he didn't have a 6 V starter and not a starter/generator. But I never seen a 6 V starter with a belt pulley, so that kind of kills that idea. Wish I could have got the whole tractor but he had sold the frame and transaxle to another party. I still came out way ahead on the deal. Hood, dash with tower, complete engine less St/Gen, rock shafts for a deck, hood with one dummy lenses, and the best part, a real nice blade for an XL series tractor. $125 + $25 to haul it about 75 miles for me.
