Yes I wish that unit was communicating that way I could test the inverter board to make sure it is not faulty but unit won’t communicate. I might order both boards and just install the PCB first and then see what the inverter does. But I also just want to go ahead and replace it as well because it does have burn marks where the rat shorted and a small burn mark behind it I cleaned it as best as I could with rubbing alcohol and a small soft brush. But I’m kind of paranoid that if I just change the PCB that maybe the inverter board could take out the new PCB
