Has anyone ever seen where the camera and radio flash when the ignition is on? It appears to be a bad ground or relay. When the coach is running I can hear a clicking sound that sounds like a relay if the coach is not running but the key is on. The radio and camera won't flash when I push the power button several times and/or menu and appears to recover and be OK. I tried turning off the house switch and that didn't make any difference . The chassis switch cuts all power so that can't be done for testing. Connected to shore power or not doesn't make a difference either.
