I attempted to repeat the test running all 3 TVs, both Refrigerators and anything else that was plugged into the Inverter's Circuits.
However, what I learned is that with House Battery Switch OFF, the inside Norcold Fridge would NOT start
After some thought it made sense because I believe that unit also requires 12vDC to operate, since House Battery was OFF, there was no way to get the 120volt load on the inverter.
So I ran with every thing else and was only able to get about 250 watts. I did plug in a wet and vacuum but it pulled too much and the inverter shut itself down and showed error. I reset and just allowed to run Inverter with what was in the coach, and 30 minutes later the Inverter and the Ant / Cable LED went off.
It sure acts as if whatever it is on some type of time delay?
Surely someone's coach does this? This was a brand new coach with about 600 miles when I bought it, so whatever it is, it is factory wired!!!
