Thanks for replying. Could you explain coach vs. chassis? Sorry. 2011 Holiday Augusta 25' Class C. When I disable the house batteries(coach?), the red light by the switch goes off, and the step doesn't work. I assume the step is powered by the coach (house) batteries? I understand that that shore power and generator will light up the coach, but without either, shouldn't I be able to "light up" the coach? The DC circuit (fuse) panel is located adjacent to the AC circuit panel. When connected to shore power, or when the gen is on and the AC circuit breaker for the Main and Converter circuits are on, a green light flashes on the DC fuse panel. As I would expect, if I shut off the converter circuit breaker, the green light goes out as well as the coach lights.
"Coach" batteries are the ones under the hood that start the engine. As someone said, likely they power the steps.
"House" batteries are the ones located somewhere under your motor home. They power all the 12V stuff in the RV--water pump, lights, fans, etc. If they are disconnected, and you have no shore or generator power, none of the 12V stuff will work.
The 12V Side of Life is a great resource to help understand all this.
