I am a new member, just bought a '94 Marathon. On the panel in the bedroom it shows 115 volts coming in on both phases but am only drawing amperage on phase one. The front two air conditioners and cooktop stopped working. I have the same condition when the generator is running. I had new coach batteries installed two weeks ago. I have 12.5 volts on the 12 volt system but only show 5 volts on the 24 volt system. Any ideas will be appreciated. The bus is at a local rv center now, but haven't heard anything back yet.
