Your power converter is probably okay, since the lights are getting bright when generator runs (and probably when plugged into shore power). A coach that is as experienced as yours is probably going to have multiple wiring issues that have occurred over time. Corrosion on battery terminals is common, but so is not maintaining the batteries. Batteries are usually killed by not charging properly, discharging too deep, and not keeping them clean. The batteries can also be wore out, especially if they are more than a couple years old and spent a lot of time sitting in the back lot.
Start by looking at the cables located at the battery, as well as at the battery connection on the DC fuse block. Everything should be clean bright and shiny. If not, I would suggest loading a dremel tool with a brass brush, and clean all wires and connections individually. Make sure everything is turned off in the coach to minimize sparks. While you have the cables off, take a look at the date codes and check the water levels. Correct accordingly.
There is a possible problem that can be at the converter as well. When you supply power to the converter, a solenoid engages a switch that transfers power to the batteries, charging them. If this switch has failed, it will cause same symptoms since batteries are not being charged.
The chassis / starting battery may not be charged by the house charger at all, especially if there is a Emergency Start / E-Start / Boost button on the dash somewhere. The engine is able to charge the chassis battery and the house batteries through a big relay (looks like ford starter solenoid on coaches like yours).
If you drive down the road, and main battery doesn't charge, and house batteries don't charge, Look closely underneath your coach for a grounding problem as well as possible bad alternator. But, if your house batteries charge off the alternator, then your problem will likely lie in the switch on voltage converter. If chassis battery charges and house batteries don't, look for 30 amp fuse between house battery and relay on firewall of engine compartment.
Make sure you wear old clothing, wear eye protection, and gloves when around batteries, and also when using the dremel.
