My wife and I decided to swap out the smoke detector in our new house (built in 1991 but owned for a year by us) and when pulling the detector down a wiring cap fell out, and we have three sets of wires (hot, neutral, ground, 2 each) and three separate hot/neutral/ground wires from the old smoke detector. The cap that fell out belonged to one of the separate sets of hot/neutral/ground, but I don't know which one. This disconnection has caused the ceiling fans/ceiling lights to stop working in two adjacent rooms. The new smoke detector works just fine, it was just a straight wire-to-wire swap.So I'm thinking that one pair of wires in the smoke detector box links up the two ceiling fans in the two rooms together to the main circuit of the house, but I'm at a loss as to which pair. Initially, I spliced all three pairs together (hot to hot, neutral to neutral, ground to ground) with caps, no joy. I then de-spliced them and spliced together just the black hots, still no joy. Am I missing something here or doing something wrong (clearly I am)? via /r/DIY https://ift.tt/2HDr3Pi
