Still no luck :-(
Thanks for the tip. Got a fuse from a Ford Dealer, still didn't work. Called RV dealer, they don't answer phones or emails. Called Thor Customer Service, told to get a fuse. Finally called a Ford dealer that is 75 miles away that will deal with an RV and an E450. Appointment on Thursday. all for a 12-volt dash power supply. Just one of 5 months of fixes on a new rig.
