Hello from Myrtle Beach,SC

I have a 2003 650 Rincon with some electrical problems. It has been running great since new with no problems and the other day while running it died.There is no power to anything. Checked fuses and all where fine, on the main fuse #1 I am not getting any voltage but I am getting voltage to main#2. I unplugged back between battery and fuse block and i am getting 12v. I unplugged between key and fuse block and i am getting 5v. Key switch seems to be working fine. Any suggestions? Thanks.
