My yamaha generator and PSW inverter (which I plug my shore power cable into) both show open ground with the little tester. Any interior outlet will show the same open ground result when the TT is plugged into the gen or inverter. When the TT is plugged into true shore power, tester shows all systems good
Sounds about right. Your genset probably has a floating neutral. It should say right on it. I know my Honda does. I'd have to meter the outlets to see if the ground is even connected to anything. It might not be. As for the inverter, if it's a portable one it might be using the same connections.
Cheers!
