It's been in the driveway and I have it plugged into a 30 amp outlet. Unplugged it today to move it to the side yard and all batteries are dead. Everything thing in the coach has been off but the refrigerator which should be fine since its on shore power. Checked breakers and fuses all good. The fan on the converter is running so I would think the batteries should be charging. Not sure what to check next.

Usually the problem is the Master Power is in the store position. If you have an inverter you can check the voltage to the batteries. If the master power is in the store position the battery voltage will be less the 12.8 volts if the master power switch is in the use position the the voltage will read 13.0 volts or more. The light in the switch only shows the switch has power but not the position of the latching relay located under the bed by the power center.
