I replaced my altornator and now my radio lights up but no sound. The fuses are good and I unplugged the phone connector to see if that was it but nothing. If I put the key in and put it on acc the radio has sound but as soon as I switch it to on or crank it the sound turns off. Any ideas on what I should check or do?

 

a relay or fuse is bad, also check fusible links.
