I have a ceiling fixture in a bedroom that doesn't work -- and stopped working about the time I had replaced a light fixture in the hallway adjacent to the room.

I took the fixture in the room down, tested to see if there was power, and low and behold, neon bulb tester shows power between neutral and ground, as well as hot and ground, but not between. I assume this is an open neutral?

If it is, considering the two fixtures are fed from completely different switches, do they share a neutral?

So if this is the case, I assume I need to figure out what I left loose when I installed the new fixture.

Just making sure that's the course of action, before I start tearing more tihngs down.

Thanks

 

Yep, sounds like an open neutral.

Yep, they could easily share a neutral.

Yep, you need to figure out what you left loose.

Make sure you know how to identify a switch loop before you start. When a switch loop is used, not all white wires are neutral.

 

it worked, thanks for the help ... left a loose connection when installing the additional fixture ... tightened the wire nut, and viola.

thanks again
