I don't know about your particular coach but I had the same problem on my previous coach and the inverter switches to charge when plugged and that portion of my inverter went bad. It wouldn't charge the batteries and they would run down causing problems numerous different problems inside the coach.

Check voltage at batteries with and without converter turned on. Should be about 1 volt increase when on if working. If no change check input and outputs at the converter.

Measure the voltage at the battery terminals when connected to shore power. Make sure the battery disconnect is not in the disconnect position. You should measure about 13.6 volts if the converter is good.

If you find the charger is bad, and not just something that needs resetting. You might want to look at just adding a Battery Tender for keeping the house up while plugged in. We had a 98 Bounder and the Battery Wizard stopped working. I bought two Battery Tenders, and permanently mounted them to support the House and also the Chassis batteries. I ran an extension cord from the house batteries to the chassis batter area with tie straps, and then had only one run from the garage to the house battery compartment, where I used a three way plug to feed the house Battery Tender and the extension cord up to the chassis Battery Tender. (Left these in the coach when I sold it, and wish I had pulled them out!

Best of luck,

I found out the charger/converter was disconnected. I pulled it out and measured the VDC and it was 38.6 without being connected to the system. Should it read that high or at the most 13.6

Depending on your meter and the rectification and filtering of the converter it very well be fine. Connect it to the batteries and measure again.
