I have a 2003 Coachmen Catalina 29 FT Class C. When I plug into electric the coach's ceiling lights do not come on shouldn't there be inverter for the coach to make 12 volts. Thanks
What about the 120 volt devices? Does the micro wave work? What about receptacles? If they work it narrows down to the circuit feeding the converter or the converter power getting to the 12 volt DC distribution panel. Have you checked the fuses yet?
