Somewhere???? the VR's metallic case has to be grounded like to the generators body (or else the tractor) cuz it provides the field current return current path. Id also use a jumper wire etc to insure the genny itslef has a good ground to the tractors frame as paint or rust can cause a resistive connection. I dont get into VR adjustments over the net, it involves fairly close air gap and spring tension settings and I have NO specs or data here. Maybe Jim or Bob can help with that?? Only thing I try is to non abrasivley clean/buff/polish the VR relay points in case they have oil or oxide or residue hanging on. NOTE a well charged good battery isnt supposed to keep drawing high charging current, maybe a VR relay point cleaning and a lil burn in "washing" of the VR may get her to working?????????

Other minor cheap n easy things (besides grounds n connections) to check are the brush hold down spring assemblies arent stuck or corroded (clean n lube n exercise them free) or the brushes arent worn down short or the commutator isnt all oiled or blackened over (clean it up shiny)

Let us all know
