If I'm understanding this correctly, it sounds to me like your convertor is working and charging those batteries. Those interior lights are 12V and running off the batteries, not the 120V shore power. If you turn your battery switch off the batteries aren't being charged and your lights will stay dim (weak batteries -not getting charged?). Turning on the switch (as it should be when plugged into shore power or the generator), allows the batteries to be charged, resulting in brighter lights.
