Thank you for the responses. Because the Coach battery disconnect works, I tested the rocker switch by swapping the plugs to the Chassis switch and the chassis switch worked to the coach solenoid, so I don't believe the switch is the issue. There is a Trombetta 114-1211-020 solenoid connected to the battery side of the Chassis solenoid. I have voltage coming into that, but the outbound post is grounded. I am wondering if its this battery isolation solenoid that is bad. I have verified that all of the battery connections are correct. I don't understand how the Battery side of the chassis switch could be grounded.
