It doesn't have to be visible. It messes with the control circuit and transformer. What you are describing is typical of that kind of problem. That's why I went out on a limb and mentioned it.I’ll have to go pull it out to check the model. Assuming it’s not a X series, what kind of damage are we talking about? I saw nothing burnt on the board.
Generac, if you call them, should have an idea what THD that model puts out.
