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.
No. It is working as designed. It goes to zero because there is zero 12v voltage.
Just because it is plugged into shore power doesn't mean it should show full charge should it?
Yes, it should. Plugged in to shore power, your converter is producing 12 volts so the monitor is reporting 12v. The monitor can't tell the source of the 12v, battery or converter. It just says 12v is here.
That makes it entirely useless for checking battery levels.
Its purpose is not to check battery levels. Its purpose is to report if you have 12v available to the coach. It is doing its job as designed. If you want to only check battery levels, you will have to run a separate monitor directly to the batteries. But, it will require a separate disconnect switch.
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 label is wrong. It is not connected to the batteries. It is connected to the RV 12v circuit and shows the voltage of the RV circuit, not the batteries. The only way it reports on the "battery condition" is to turn off the battery charger so the only 12v available is from the battery. THEN and ONLY THEN does it report the voltage just from the batteries.
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.
Nothing is miswired. Your understanding of the wiring is incorrect.
