I just moved into a house and I am trying to figure out an outlet-switch issue. I have a bedroom with a switch that does nothing. I figured it controlled an outlet, so I found an outlet with 5 wires. 2 black and 2 white wires and a ground. I figured they must have forgot to break the little metal tab on the outlet. I broke it-reinstalled and now top has no voltage but the bottom does. I checked voltage going to switch and both black and white wires have voltage when checked against ground. Any ideas what to look into next? Thanks
