Smoking Batteries
2010 Springdale 26BHS: When I plug into shore power (30amp) I wake up the next morning to overheated batteries that are smoking and putting out that wonderful smell. Here is some history: years a...

You will need to know what state of charge the batteries have. You will need to know the voltage set points of the multi-state charger you have. 14V may be the absorption set point.
If the batteries have a full charge, the converter should not output more than 13.6V. It is unlikely you have a 120V problem as the converter is outputting some charge current. They typically fail open or not outputting any charge even though 120V power is present. A converter failing in the 120V power circuit would likely trip a breaker.
My internet diagnosis is that you have a failing battery or wires connected incorrectly. It is possible to have larger DCV with a failing converter but it is rare.
