The 250's battery was flat, charged to 12.4v, started but meter went to 17volts! New battery installed but still overcharge. I'd say stator is not issue with all that voltage. I'm thinking weak battery damaged regulation circuitry. Anyone else familiar with this issue. My 300 and sv650 have same unit but are working fine (crossed fingers).
