About 3 weeks ago my wife wanted to turn the radio on, but nothing. Really didn't give it a thought, until I went to start the coach Saturday and the engine batteries were dead. Flipped battery merge on and a couple days later got ready to start the coach and just happened to check the radio - which is now powered. 

My question is, what else "in" the coach is powered off of the engine buss that hot even when the key is off?
