Put a volt meter on your batteries, then press disconnect on your chassis remote battery cut off switch. Note the readings before and after. You should see appx 13.6 volts slowly go down to battery voltage appx 12.6 volts. On my coach the battery light stays on when using shore power, but the remote disconnect actually works! The reason the chassis light stays on is because the monitor is tied into the coaches electrical system before the shut off solenoid for the battery, so the convertor power keeps the light on.
When your batteries are fully charged you should be getting a rested voltage reading of appx 12.6 volts. The battery state of charge indicator inside the RV will show a full charge whenever it is connected to shore power wether the batteries are low or not.
