Montana ft inverter, trying to figure it out
I can't figure out the inverter for the residential style Samsung fridge in my 2017 Montana. I know that there's a disconnect switch specifically for the inverter, I know there's an on/off button on the inverter, and... I think that's everything to the inverter that I know about. So, basically I turn it on, it reads the voltage of the battery on the display, then it flashes "0.0" then reads the voltage again and it keeps alternating like that. Not sure what that means. I'm not getting any power from the inverter's outlets. I've tried a phone charger and it also didn't work, maybe the inverter is broken?
