We do have a salesman switch, which has been tested and is working. The light indicating it is on does not work, however. When the switch is activated it makes a clicking sound somewhere in the rear of the coach. None of the lights, frig, slides etc are operating.
The coach was at the dealership a few days ago to fix a completely different problem. When it left our house, the dc power was fine. When we got it back, it wasn't working.
We also wondered if there is a manual DC on/off switch somewhere (besides the salesman switch) that was turned off by the service people.
The service department at the rv dealership has not been helpful, stating that the solenoid "could be anywhere".
