well it all started by installing a radio in the xj and finding that the constant power wire was dead and i cannt figure out why so i ran a new one leaving the rest of the wiring running through the harrness

then yesterday the radio had power and continued to play tracks from the ipod everything looked to be fine but i had no sound so i thought ok i lost a connection but in my down time at work today i checked everything out and all was fine still no sound

then when i got home tonight i opened the door and the door buzzer worked for the first time in a week and then the sound came back in the radio but as far as i know the radio isnt tied into the buzzer so why the sudden change?

fuses are good wires seem to be good all butt connections for the wiring seem good

anyone else had this problem or might know what would cause it?

 

Try grounding the frame of the radio with a good solid ground. Find a screw or bolt that's for sure in metal and use a minimum of 14 gauge wire to make the connection.

See if that helps.
