Now I was riding home today and on the last leg of my journey my bikes speedometer jumped around, odometer went out, so I decided to try and make it home. But i was losing electrical power to run the fuel pumps and light were dimming. Battery died. I jumped it off so I could take the volts from the electrical system and when running i was getting 13.10 to 13.60 volts. Does it sound like the Battery Old, Stator or something crazy.
