Clock over bed flashes cannot set to correct time. Time sets for 5 to 8 min then starts flashing "12:00" again. Any suggestions. Coach is 2005 u320, 40 ft.
Sounds like intermittent loss of power supply. Remove the clock from the panel and check the wiring connection on the back side. Loose connector? Frayed or damaged wiring?
