What am I not doing right? I had assumed you could leave it plugged in and it would just maintain the batteries. Thank you in advance.

The light on the master power switch only shows the master power switch has power it does NOT indicate the position of the latching relay which is under the bed. If the is no power to the coach and if the interior lights will not come on using the switch, the latching relay is in the off position . Other than a voltage monitor, this is the only to ensure the latching relay is in the on or off position. With a voltage monitor or VOM, you can easily check or the battery's condition and the converter's output. If the master power on and the converter's working, the converter's output to the battery will be 13.1 to 13.5 volts depending on the temperature of the converter. If the house battery is low, the voltage may be as high as 14.3 volt during bulk charging. You should never see voltages above 14.5 volts unless the batteries are being equalized. This option is only available on the more expensive MC.
