FYI - left this morning and all worked out fine, albeit NOT optimal. Under same conditions (just overnight, needed AC, no availability nearby, GND bonding issue NOT hot/Nuetral problem, etc) I'd do the same again. Would not have done this without DVM and understanding that L1/L2/Nuetral were good, also would not advise someone else to do what I did.
With that said, pretty sure CG has been that way since "fixed" and lots of others have stayed there unknowingly without problems. Maybe someone has had a problem, but pretty sure most haven't. Again, NOT saying it's OK. But I did understand the situation and limit my exposure (ran minimum amount of items w/GND) and the calculated risk paid off. Still better not to take unnecessary risks if you can help it.
FYI, I do know a little bit about the issue at hand. I've wired a few houses, including replacing main panel etc, and have a EE degree. And darsben1 - I still appreciated having my surge alert me to a situation that I could investigate further and appreciated the surge protection it still provided (even though not needed).
Just posted this to gather others experience and knowledgeable recommendations, as well as to add my experience to this body of knowledge. Thanks for comments.
