For those looking for a pint size Alternator because of room issues, our Denso Alternator shown with our CNC machined 5/8" wide belt pulley, and quick disconnect module is the ticket! This 3 wire unit works great on board any Tractor.  Brand new unit ready to go. 35-40 amp rated. The same unit that comes in our 12V conversion kits for the C,CA & Model G Tractors where a large "SI" series Delco Alternator will not fit.
