I recently replaced some of my home’s light switches and outlets… some dimmers, 3 and 4-ways, a few GFCIs so nothing overly complicated.
After turning the circuit breakers back on, the overhead light in a separate but adjoining room does not work. It is controlled by two 3-way switches in that room only, neither of which were replaced nor did I replace any of the duplex outlets in that room. Any idea what I could have done wrong? thanks
Unlikely there are multiple bulb failures, I agree.
If you don't have a voltmeter, go get one. Such a tool is practically a necessity if you plan to do electric work, even projects such as this which are not overly complicated. Without one, you are troubleshooting by trial-and-error. This is no way to work.
