I have a 3way switch atthe end of the circuit. I tried to come off that switch to a 1 pole switch to controll a new ceiling fan that is only going to have one switch. I ran 12/2 wire from that new swith. The 3way still works the same and the new switch turns the power on and off to the the new ceiling fan/light, but nothing happens at the light (nospin and no light). My tester shows the power does get tothe light socket and fan motor. What could be wrong?
