Javelin, I don't think I have the BCC. I believe I have resolved that part of the problem by replacing the house batteries. I thought it was the battery isolation relay, (the one that clicks when use/store switch is engaged) but while troubleshooting I found a slight leak in one of the batteries, and they would never charge to over 12.4 volts. When I replaced them and got them fully charged, it resolved the problem. The isolation relay is still acting kind of finicky, so I ordered one from Amazon to have on hand. The batteries going completely discharged while at the dealers didn't help matters any. I'm curious about this BCC, it's possible I have one and just haven't spotted it yet, I keep finding gizmos all over the coach. And the compartment under the bed where the converter and inverter are is a wiring/component nightmare.
