After getting the SM started again following a carb rebuild, I turned to the electrical system to troubleshoot the lack of charging. The VR output had been adjusted and the gen inspected by an auto electric shop - both had a clean bill of health.
The ammeter showed a slight discharge with the ignition switch on and the needle didn't move with changes in engine speed. Following Bob's troubleshooting flow chart, I made it through to the last step before the ammeter began showing a charge.
