Yesterday I was planning on meeting my wife and her friend down at the local pub after work. Jumped on my bike, turned the key and nothing but an irritating loud buzzing noise. I checked the source and the sound comes from under the plastic electrical cover on the right side of the bike. I checked all of the connections and fuses and they all seem too be in order. Do I need a new battery or is is their another problem. Please help! I do not want to take her to the dealer.

Thanks
