to the forums. As for your problem, need a little more info. How do you know that light works if you have no power? What have you tested and how? Do you have and know how to use a voltmeter?.
Sorry for all the questions, but no one can answer your question at this time. You will have to be the worker, and people here will tell you what to check and how, so if you have checked some things, please post it, so we don't start on the bottom floor and you already on the 5th floor. Help will come.
