Well done and Cooter nailed it right out of the box as battery cable culprit. In all likelihood you'll have FC #16 stored from all this CEL activity. It will be wiped from the ECM memory after 50 "clean" run cycles.
You have 3 relays located in your fuse box. They are ACC....KEY SWITCH...START....AUXILARY(on later models). They are identical. As these Buells continue to age it's a great idea to place a spare relay and several assorted mini-blade fuses in a very small plastic bag and secure it somewhere in the vicinity of your battery box for potential roadside repair.
