Willie,
Unless you have a house electrical system that is very different than anything I have seen either in boats or RVs, the AC power (be it from the genset (APU) or shore power has almost nothing to do with the things like lights and pumps that are run on the DC power.
Yes, problems with the batteries and converter could possibly be it, but you did the right thing there.
You say flickering, but you don't say if that flicker is connected to anything else that might be happening. If it continues after you have checked/cleaned/tightened all the connections you can find, then go looking to a load that has activity that is sort of connected to the flicker. I had to solve a problem for an owner once that though he had a random flicker, but when I sat there long enough, I realized that it happened every time his reefer kicked in. I was electric, but it was have a bad time starting and drew down the power when it did.
