We have a 2007 Fleetwood revolution. It is plugged in all the time in a 3 sided building. ( front is open, the unit is back in) It makes a chirping noise. It looks like everything is normal when we go...
Something easy to check is make sure your downriggers are up all the way. in my old coach the would leak off just a little and then the chirp would begin. get in crank it and pull them all utp and see hope this helps
