Well Gang,
I did check the voltage and it was perfectly fine. The King Dome is known for many issues. The staff or, techs they have are and have not been helpful in most cases. Only once in a while is someone satisfied with the tech help when addressing King Dome problems. My son works at a local RV Service Center here in San Diego and they have a "Pile" of King Domes that have been removed due to malfunctions of many types. They install the Traveler about 99.9999% of the time and it's always right on.
