2001 Discovery 37-u. 20 amp fuse for Dometic fridge, exterior porch, entry step, entry overhead, kitchen d/c florescent light, and four area lights blow when unit is moved. With fuse blown the Fridge will not function on gen, shore power, or gas if the panel is not functioning.
Parked, new fuse, everything works fine. Had 2000 inverter/charger rebuilt last January and was parked for 3 month with no issue. Problem started after driving unit. Have tried shutting off all known d/c supplied circuits before driving and fuse still blows.
Have disconnected, re-attached, and tested all circuits while parked and found nothing. Service center says possibly is wiring and want to trace by removing ceiling and walls in areas of concern. Possible $5,000 to $6,000 in labor. Any suggestions?
