Moving ceiling fan - interesting problem
I am in the process of moving a ceiling fan from one room to another. The fan's new home previously had a fan installed so it is already wired. The wires are not powered through a switch but are connected to a junction box in the attic. Here's the issue: With the breaker on I show power in the wires coming out of the ceiling using an ac voltage detector. Breaker off, installed the fan, breaker back on, and now there is no power in the wires. The breaker does not trip and everything else on that circuit works fine. If I disconnect the fan and flip the breaker back on, there is power in the wires again. The fan worked perfectly before this. WTH?

Welcome to the forums!
Yes, that is interesting. Some more specific information might help us assist you:
Yes, that is interesting. Some more specific information might help us assist you:
- How are you determining that there is power, or not, and
- How many cables, how many wires in each cable, and what color are those wires, in the ceiling box?

If by AC voltage detector you mean a non-contact tester then that is the problem. They are useless for any kind of serious testing due to false positives. You need a test light or analog multimeter for testing voltage.
