I replaced 2 wall outlets and a light switch in the dining room. I pulled and replaced the wires in the back of the new as I was disconnecting from the old to make sure they were in the correct sequence. When I turned the power on, the light and fan in the ceiling work, but the outlets have no power. Our living room outlets are on the same circuit, so now I have no power to outlets in two rooms. I've heard about reversing the polarity of a house and screwing things up, but I followed the previous wiring. Any suggestions?
