Can anyone help me in getting a wiring diagram for the 12V Battery system in a 2009 Holiday Rambler, Ambassador, 42 ft, 360 ISC Cummins? I have no 12V power in the unit and I have checked the battery disconnect, I have good batteries, and was told it could be a fuse between the disconnect and the switch on the inside of coach to turn on power. The solenoid appears to be working when you press the power button. You can hear it clicking. Any help is appreciated.

You have battery into solenoid do you have 12v out other side of solenoid.
Contacts could be short inside solenoid.

Holiday Rambler was bought out by Monaco.

Thanks to everyone for the advice on the 12V. We have it fixed. It turned out to be a hot wire going from the AC panel to the 12V panel had come loose and was laying in the cabinet behind the 12V fuse box. All of the information provided was very helpful and was in line with the advice from Monaco.
