On my coach, 05 Marathon, if I start the engine while the shore cord is plugged in, the equalizer light will come on. It has to do with two ways of charging the batteries at one time. This is normal and nothing to be worried about.

Agree, however both battery banks, 12V and 24V are charged together with alternator and inverters. When both are charging at the same time, is when the problem occurs for me. The Technology could be a lot different in our coaches.

When the coach is plugged in, the inverters are charging the batteries. When the engine is running that is another means of battery charging, the alternator. On my coach that will show up as a battery imbalance.
