My 2003 Adventurer has a dash mounted switch for engine battery or house battery for the radio in house mode it does not work I have no power on the memory lead or the main power lead. Engine mode I have power on both those leads. Where would the relay be mounted? Works when switched to engine power and the key is on or acc position. Or is a fuse somewhere?

Here are the full Wiring Diagrams for your coach. The Automotive Wiring Diagram shows the connections to the Radio Power switch. Each 12V wire should be labeled every few inches--you can look up the labels in the Wiring Identification Guide. I would check the wiring on the back of that switch and compare it with the wiring diagram--you should be able to trace the wires back to the appropriate fuse/breaker using the diagrams.
