Another possibility:
IF....it is really reaching a 30 amp current, then the current limiting function in VR would try to protect the 20 amp generator by reducing or stopping charging. Then when reduced , it tries to resume, thus oscillating between excess amperage and little to no amperage. Maybe caused by bad battery, bad VR, etc.
