I just had a new tire installed on my 1996 1500 Goldwing, when they tried to start it the battery was dead so they tried to jump it so I could at leased get it home. But it still didnt start and the wires going to the battery tender melted. I removed the melted wires and installed a new battery, and it starts great now but now my stereo is at 1/2(at best) volume. I was told it might be in the mute switch but the tuner up/down works and so does the mute switch on the handle bar, but the mute on the tank doesnt. (do they both do the same thing?)anybody ever seen anything like this? Ive tested all the grounds I could get to, no melted or damaged wires that I can see. Any recommendations are appreciated
