I took out the battery. And after I was done changing it, I went for a ride. After a bit, I turned on the radio and had no sound. So, I got home and turned it off, then turned the bike back on w/o starting it, and the radio and volume came on? I did notice the avc was off. I don't know it that was the problem. Anyone have any other ideas. Now last year I did put in the JVC speakers and amp. So I did run the wires under the tank.
