BigPete -- Can you give us the model of your converter/power panel, or post a pic of it with the front open?
Be sure the shore power is off and the power cord is unplugged. Then pull the converter out of the wall and test the voltage at the battery terminals on the unit. Let us know if you have 12 volts to them?
