My generator used to run 2 RV airconditioners, now it will only run one. I measured output voltage, it is 113 volts no load. I measured the hz also and the confusing part is that the hz vary from 136 to 312. When I shut the generator down and use power from the house the same outlet measures 60 hz. What would cause the hz to be off that much? What should I be checking? |
