Ok the batteries test 14v and on RC6 showing the same voltage, I disconnected the phone like jacks are clean and the inventor dint not turned off by disconnecting the jack, the state of the invertor now is working ok, green light and all green on the RC6. now the question I am left with is? why the inventor and the RC6 went black for 4 days will the lighting was not affected? and again for 2 days after that incident.
