I had two black and two white wires coming from the ceiling. I guessed wrong the first time and hooked up the wrong black/white combo to my fixture. It didn't work.

Next, I capped those off & hooked up the other black/white wire combo to the fixture. This worked, but then the strange thing happened: A nearby light quit working.

This light always worked along with the old lights that were connected to the ceiling fan. Now, the new lights were working, but this other nearby light wasn't.

I checked and it wasn't the bulb. So, I took down the new light fixture. I had capped off the "extra" black & white wires. This time, I capped them together, thinking I had interrupted a circuit that provided power to the nearby fixture. This did nothing.

Next, I just tied in the "extra" black & white wires along with the other ones so that BOTH sets were connected to the light fixture. This did the trick. The new light fixture worked & so did the nearby one that had stopped working.

My concern now is that there might be something dangerous about having both sets of wires tied in to this light fixture.

Any advice is sincerely appreciated.
