Hi, thanks in advance for any help...I am remodeling my 1950s bathroom. I am replacing the old duplex receptacle (not grounded) with a new grounded one. In the same box is a single pole switch, also being replaced with a new one. I hook everything up (new) and the there is power, but when you turn on the switch the overhead light won't come on. If I hook up all the old, it works fine. There is power, but the light won't come on. I'm so frustrated. Please help! Thanks!
