Hi. new here. I have a 1968
30'sovereign I have used for several years as a deer camp and only used 120v power, there is no battery in it, but does have a converter that hums. I am redoing some of the inside so we can use it for summer lake camping as well as deer camp. I have no need for the 12v
power. During remodel I removed the big control panel that has all the systems checks on it and disconnected all the wires, thinking it was only used for the 12v
side of things and I would not be reusing that. Well now I have no power to anything and the converter sounds like it is still working. Can anyone tell me if that control panel has to be connected or what might be wrong? All outlets were working fine before I removed it and now nothing.
