I have ceiling fixtures, let's call them A and B. Normally, both fixtures are always on (lit) -- no switch controls them.
When I remove the bulb from A, fixture B goes out.
Fixture A is at the top of the box. Fixture B is the one on the bottom (I think, not 100% sure about that.)
As you can see, the white wire from Fixture A is connected to the other white wires in the junction box. That makes sense.
But, the black wire from Fixture A is jumpered onto a white wire, that's then connected to the white wire on Fixture B.
What's going on here?
I plan to put motion-detector bulbs in both fixtures, so I want them both hot all the time.
Can I just remove that white jumper wire and connect the black wire to the other black wires?
I have confirmed that there's nothing wired downstream from the Fixture A box - the wires terminate there.
