wondering if anyone can help. i'm putting an addition on the house, and i have all my lights and switches wired up. i ran all the wiring myself and double checked it all. however, my two exterior lights and my ceiling fan will not operate unless the previous light in the circuit is turned on. i have all my commons connected together and in the switch box for the last properly working light, i have my three black wires tied together. one is my incoming hot, another goes to one side of my switch, and the last goes to the next switch box for mu remaining lights. i just cannot see how i am not getting power to the other lights with out that switch being on. CAN ANYONE HELP?
