If floating your ground alleviates the symptoms, a small voice inside my head is telling me you’ve got a ground loop somewhere. That can cause weeeeeird stuff in sensitive electronics and was the bane of my past life in the AV world.

Not our chair, not our problem, except our portable generator gfi trips every time the cutover switch engages. We ended up just bypassing the cutover and only wiring phase and neutral to the generator outlet, leaving ground disconnected. I suppose we could have left everything intact and disconnected ground from the panel, i dont know But what we have now is phase and neutral on generator feeding the outlet up top, the ground is still connected to the service ground up top. We dont have access to a panel its connected at I did measure between the ground at the panel and a known good earth ground. No voltage, i assume that means no hot ground. The concern here is if im missing something and the gfi is kicking because of something i dont have capacity to verify, is running this generator this way a risk of electrocuting somebody who touches the frame? Its ground is not connected in the circuit, same as if id just connected a 2 prong adapter
