I unpluged from trickle charger and tried to start. I turned the switch on tank lights came on. I hit the switch on handlebars and heard fuel injection. Hit the button to start and everything went dead. checked battery and all connections and tried again. turned on switch at gas tank and heard buzzing behind battery. I could feel it. It was the relay on the left side behind the battery. I replaced it and still have the same problem and same buzzing. Please advise what to do next.
