I was attempting to install a ceiling light in my living room. The house has old cloth wiring. The box I was hoping to tie it into has two switches: One was for my porch light, and the other was for the outlets in the room (not "switched" outlets, mind you- the switch turns all of them on or off). I ran 14-2 romex to the box, and added a dimmer switch. I updated the other two switches, as they were fairly old. Once I'd hooked everything up, the porch light was working, but ONLY when the outlet switch was off. The indoor light switch didn't work at all, though there was current running to it. I tried unwiring the porch light, and that resulted in the inside light working, though extremely weak, only when the outlets were switched off, and the dimmer had little to no effect. Prior to messing with this at all, the porch light and the outlets were able to function completely independently. Any ideas what I'm doing wrong?
