I have 3 rooms on one circuit, 20 amp. Lights only. 2 rooms only have light fixture in ceiling and mstr. Bdrm has new ceiling fan with light kit. Ran new romex 12/2 wiring from circuit panel to junction box. From junction box went to each room. Got room1 working by running whitewire (hot) to bottom pole of switch. As I read on another site. Used identical instructions in bedroom 2 and it won't work. Same with master bdrm. Nothing at all. Can some one Please help me 2 get this wiring correct? Any and all help is much appreciated.
