Ron: Question; your posting is titled "generator grounding problem", what makes you suspect there is a grounding problem with the generator or did you mean something else?

I assume you are now hooked to shore power and only the kitchen and TV are working. If you are comfortable working around 120V electricity I would start at the circuit breaker box and see which circuits have power and which don't. I suspect that one leg of your box has failed, if true then you will have to trace that leg's wiring back until you find power and know where the failure occurred. After fixing that, I would turn all the breakers on that leg off, turn the power back on (I'm assuming you know to turn the power off prior to repairing the wires), slip a amp meter on the supply to that leg and watch the meter as you turn circuits on one at a time and then off again before turning the next one on. It's possible that there are other problems lurking downstream of the circuit breakers but maybe not.
