I'm not familiar with the B.. but I do have a cub with a vr, and i also have other tractors that use a genny with a cutout only, and have a lamp switch that has a ressitor to tickle the field when lamps off ( low charge ).. and when lamps on, the resistor is shorted, thus making hi-charge.
Using a VR for field current controll is MUCH superior.
I would connect the gennies field pole to the VR field tab. Gennies armature to the GEN/arm tab on the VR, and then that leaves ground which is obvious ( if you have a 4 tab vr ).. and charge line out to the ammeter.. etc.
If i remember correctly, that genny is A-Circuit, meaning it's field is internally hot, and the field terminal is looking for ground. make sure you have the correct / compatible regulator.. etc.
