Sportscoach 12 volt issues

I have 2004 coachman sportscoach 40ft diesel. The chassis batteries were dead and I hit the battery auxilary button on the dash to try and start it. When i did that it kicked something out and now I have no 12 volt power at all. I replaced the chassis batteries and I am back up and running. Now everything works when the ignition key is turned or the engiene is started but when I turn the key off...I have nothing...the generator will even shut off when I turn the ignition off. Again ..everything worked fine (house batteries are new also) until I hit the battery aux button. I am not sure where else to look. The big fuse in the house battery compartment is working.. I also have 12 volts at the inverter. Is there another relay or main 12 volt fuse that would kill the entire house? The battery disconnect switch inside the door will not light up unless the key is turned..and it will still shut everything off. ...any suggestions? If there is a selenoid I have not been able to locate it...any help would be appreciated...thanks JIm

Not sure about your Sportscoach, but my Dutch Star has 2 , 135 amp fuses on the frame rail behind the battery bay, one for chassis , one for the coach, to protect the main cables that run the length of the coach to power the dash end systems. Might be worth a trip under with a voltmeter and follow the main coach batteries power cable till you find your bad spot. Disconnect your chassis batteries , so you don't confuse the systems .
Good luck, and I say this because with electrical problems I'd rather be lucky than good.

Thanks Skipp...I have been under with my trusty meter but difficult tracing. I was looking for a selenoid or a fuse with no luck. I will continue to look again tomorow.Do you know where the selenoid might be located? It wasent behind the battey compartments somewhere on the frame is where i was looking...followed it over to the inverter and it does have 12v. hmmmmmm?whats puzzing too is i can start the gen and it runs fine...turn the key off and it kills everything...i am missing something...thanks again

Look in compartment near the rear axle, passenger side for a black plastic cover. Behind this cover is the battery disconnect solenoids. The house side sounds like it is not closing. Look for a blown fuse on the solenoid or a bad solenoid. Good luck and keep us posted.
