Sounds like the genny is just weak period, maybe from worn brushes or the brush hold down spring assemblies are stuck/corroded and if its an adjustable 3 brush genny, I would be setting it for max charge n try it. Right after cranking the battery ought to be down enough that I would expect full charge for a while at least out of the VR (which dead grounding the Field provides). The only true test (if battery is okay) is what the battery voltage is doing and a good genny n VR ought to raise it from 6.3 volts to at least 6.5 n more indicatimg its charging. Those open circuit genny voltage tests dont tell me much. The only other VR by pass test is to jump the VR"s internal Cutout Relay when shes running by momentarily connecting its BAT and GEN/ARM terminals together to see if she charges and the battery voltage raises then and if so but NOT otherwise, then I suspect the VR"s cutout relay isnt ever closing. Still sounds more like a weak genny for now, check for a 3rd brush and adjust it to max charge n try her with the gennys field dead grounded and the internal cutout relay by passed n if still no charge (IF battery is okay) after cranking and light use which ought to run the battery down a bit, I suspect the genny is weak. You could also remove the belt n try to motor the genny n see how it performs?? John T
