Thanks for the replies guys. I turned off the breaker that the converter is connected to, and of course it shows zero, as the wall monitor is a 12 volt device, so it didn't work at all.
Just because it is plugged into shore power doesn't mean it should show full charge should it? That makes it entirely useless for checking battery levels.
Surely it should be showing the actual level of the batteries, whether or not I'm plugged in, shouldn't it? It's labeled "Batt Cond" after all...
The batteries are disconnected in the first place because they were way below 12 volts. The converter is not charging them, and while the batteries were disconnected to charge on a trickle charger, I noticed the wall monitor still says full. That can't the intended behavior. Something must be miswired.
