dont know alot about this bike,i just bought it with 37,ooo on it.Like an idiot i left the ignition on and run the battery down went to charge it and accidently touched positive to the frame. i know,i know but my grandson (3 yr old) is a future biker and was trying to help!Any way i changed the 1 amp the 3 amp and 5 amp fuses the cb works and the light works on the stereo face but no fm channels no display shows up and no sound, have i fried the stereo?
