BAD GROUND reading when running generator
I was checking the 110v outlet circuits when I was running my genset and I was getting a BAD GROUND reading with one of the plugin type circuit checkers. Switch to Shore power and all is good, switch back to the generator and get the BAD GROUND reading again. I looked at my transfer switch, looked inside the power box on the generator and did not see anything obvious, but I am going to keep trouble shooting.
Any thoughts on this?
