Hi There...

When you plug in the Power Converter takes the incoming AC voltage and makes DC voltage, it should also charge the battery. So if the Power Converter is bad you will get no DC voltage. Some converters are part of the breaker panel and some are stand alones and plug into an outlet. I would cycle all your breakers and then verify that you do not have any GFI'S tripped. Also you want to check for an auto breaker, the only thing between the converter and battery should be an auto breaker. Normally they put them close to the battery, if you find that you can check voltage on each side it should be close, if one side reads much higher voltage it could be the problem.... IF you know the make and model of the power converter I might be able to help you more.... Robert
