In Reply to: Installing options(?) for an 8N10000 generator on a 1941 9N posted by Lou Puls on October 18, 2021 at 16:38:54:
There is a Service Bulletin saved here somewhere that diagrams the switch over from a 9N/2N GEN & Cutout to the 8N10000 and VR. You delete the old CUTOUT and replace it with the newer 8N Voltage Regulator with the 8N- GEN. You don't use the cutout with the 8N GEN. Must have a belt tension device as well or you'll never charge the battery. Your tractor but I'd stay with the 9N-B or 2N-10000-C GEN and Cutout myself.
