Replaced the alternator and now the radio does not work... Is there some hidden ground for the radio that I could have disconnected. The clock in the radio does not work also. I checked the fuse but its ok and even swapped out the radio but everything was still the same.. Don't know where to check next. I must have disconnected something but checked everything twice and can't find anything. Anyone have any ideas?? Everything else electrical seems to work fine except the radio???
