Engine Buss - Mxfarm - 04-30-2015

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?

not sure when my Key is in the Off Position the dash/radio/leveling is all off on my '82. Someone could have changed something?

My radio works whether, or not the key is in any position. I assume it works off the chassis batteries, but I have no idea.

The DDEC and Allison transmission computers probably have a small parasitic draw from the chassis batts.

You should have a fuse list posted somewhere that shows what gets powered from the chassis battery and another for the house batteries.
