A neighbor helped me out ( broken shoulder is in a sling) and when I was in
hospital removed a working but rusty porch ceiling fan and replaced it with
a light.Which won't turn off! I called him and he said he connected white
ceiling wire to white light wire and black ceiling wire to black and there
was a red wire left over which he didn't touch.It is not and has never been
a 3 way circuit.Seems to me I can visit the switch and all do all I need to
without getting up on the ladder.
I figure that I will find Red going throuigh the switch and B and W running
past it. Which,B or W, should I connect ?I assume that R will need to be
It sounds like connecting the light to red and white instead of black
and white would allow it to be switched on/off.
Then cap off the unused black (always on) wire.
White is always neutral and is never switched.
Wrong. It's a *very* common practice to control lights with switch legs, in
which only one cable goes to the switch: the black wire bringing power to the
switch and the white wire returning switched power to the light fixture.
(-) -----white-----*-----white----- Light

I could be wrong - don't have a Code book handy to check - but ISTR that the
Code permits leaving the white wire unmarked _in_this_specific_situation_.
It's certainly a sufficiently widespread practice that it should not be any
surprise to find it so.
When you do a switch leg, I believe the wire going to the hot side of the fixture
must be black (or red). Which means that the white side of the switch is
connected to the hot feed wire (which will be black or red), and is the
As I understand it, in this particular case you don't have to mark the white
wires - in the fixture, you have one white wirenutted to one or more black/red
wires. Which means the white wire _must_ be hot (you cannot use a black or
red for neutral[+]). At the switch end, obviously both terminals are hot...

It's not just anyone who gets a Starship Cruiser class named after them.
Open it up, and describe what is actually there, rather than just a
You may be able to change the black wire, so that it is the one that is
switched, on the other hand, it may feed additional fixtures.
