2007 Monaco Knight 40 project... sigh

did you try checking the voltage at the inverter junction block in the inverter

located just above the inverter circuit breakers behind the cover with 2 screws

Yes, you need a reading the MSW volts. I panicked when I was checking voltage when I was having a problem, went and got my other mulitmeter and it checked good.

Hang in there... i knew zero about my Monaco 18 months ago, and the advice from all the able and experienced people on this forum has helped me maintain my sanity and work thru a pile of issues large and small. You seem like you've already got a handle on the main things. I will be asking your advice soon!

This may help for the tank level indicators.

Also, check when there isn't a load on the circuits. I got one of these plug-in meters that shows the voltage at all times when plugged in. I put this in my kitchen because when running a heater and coffee maker and toaster, you will drop the voltage like crazy because of the demand...might also pop the circuit. I've had to train my wife to only run two things at most at a time.

You may have two separate circuits....one for the bedroom and one for everything else. I tend to run one electric heater off the bedroom circuit and a second electric heater off the front circuit. These heaters are NOT running on batteries, of course. I'm plugged in, but I can still see a voltage drop even when plugged in with high loads. It will be greater when on batteries. I would try to keep the voltage above 110v.
