The battery disconnect (intellitec) solenoid is located in your left front bay. There are two solenoids in that bay directly in front of you as you open the door. One connects accessories when you turn on the ignition key, the other is the chassis disconnect solenoid controlled by the toggle switch near the entry door. It sounds to me like that solenoid is not connecting for some reason. There is an inline fuse in the activation line for that solenoid that could be blown, or the terminals could just have come loose. Possible but unlikely the solenoid has failed. I just disconnected the activation wire on the chassis solenoid on my rig to simulate your problem and the symptoms match. Not sure why the problem, but that's where I would focus my attention. Hope that helps.
