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.
