I am wiring a light fixture to an existing 3 way light switch. In the
junction box in my ceiling I have 4 wires, a ground, white, black, and
a red wire. How should I wire my fixture in order for the 2 light
switches to work.
Currently I have the white wire from the fixture wired to the white
from the box, and the black wire from the fixture wired to the black
wire in the box. I have the red wire from the junction box capped off.
Only one of my light switches currently turn on the new light. What
have I done wrong.
Realistically, since you're only talking about two 3 way switches, I'd
turn off your panel, remove the two switches, ohm out the wires to get
an idea of what goes where, re-connect the wires, and you'll be set.
This may be a better way...
On a hunch I googled wiring three way switch
and got a bunch of good links.
Here is one
Notice it has EIGHT different options on how your circuit may be wired.
This may help you out.
Hard to help ya since the information given is not enough to deterimine what
is really going on.
Having a red and black in the box tends to lead one to think that it was set
up for a fan and light combo.
Your going to have to take the switches apart and see what wires that they
have. If there are just 2 wires on the switch then it is not a 3 way
switch. If there are 3 wires on both switches then this is a case of
confusion for me.
If this is an existing ceiling outlet, which was connected to an existing,
working three way switch setup, you should connect the fixture to whichever
of the two wires plus ground that it was connected to. Having only one three
wire cable in the ceiling box would mean that the feed and switch legs are
already going between the switches and for some reason a spare conductor was
run to the ceiling. Try the white and each of the colored wires and see
which set works
