I have several wall mounted lights controlled by one switch. One of the
lights suddenly has no power (tested with multi-meter) I do not think this
is the last light on the run but it must be otherwise subsequent lights
would not work. What could cause the lack of power?
Your lights will be in parallel, not series, so the fact that one in the
middle doesn't work is not good evidence that the light is at the end of a
line. You could tell that quickly by opening up the box for that light and
counting the wires entering. If only one romex wire enters the box then
indeed it is the end of the line. More likely it would be in the middle.
Check the wirenuts to be sure that one of the pigtails hasn't come loose,
and check the fixture to be sure that you don't have a bad connection
somewhere. The fixture itself seems the likely culprit. Do you have power to
the wirenuts in the box?
There is one romex coming in and one going out so it's not at the end. I
tested power on the bare wires (wirenuts removed) and there is zero VAC.
This doesn't make sense to me. If there is no incoming power then the next
light should not have power???
Oh, just solved it, the light preceding it had one of the outgoing wires
broken at the wirenut.
