Now i do not know what to do, yesterday I had a power cut at 6:30 pm I started the gen still vibrating like craze, at 12:30 my wife woke me to say that the gen had cut off still half asleep it took a minute to register that the tv and lights were still on. You guessed it the gen was still running shake gone by morning still stable I have tried varying loads cannot get it to shake again
