I am attempting to install a ceiling fan in an area that previously had a light fixture. I have installed the support and box. The ceiling has 2 of the old (cloth, both black) wires coming out of it. When I install the fan with the motor and light wires connected to one side, neutral to the other it doesn't work. it has power as I hardwired another light and that works. I also put an extension cord on the fan and plugged it into a wall socket so I know that works as well. as a side note, with fan wired, flipping switch will cause a "crackle" in my surround sound system in the next room over. Any thoughts? Thanks.
