Please use some punctuation, otherwise that huge sentence can be misread a number of ways. What does "nothing" mean"? Nothing works? Nothing is wrong? How did you determine the generator is okay? Did you have it tested with a professional load tester? If so, what were the results for output current? How old is the battery?
