Light switch with 2 black, 2 white and one red wire. Switch was missing so I can't tell you how it was wired.

Its controls a ceiling fan with lights, ceiling fan is running no matter what (even with the switch gone) it will turn on and off by the chain on the fan. The wall switch appears to control just the lights on the fan and is somehow tied to one wall outlets. Outlet is normal two white, two black.

The switch for the light has one wire with black white and red, the black is hot. The other wire has black and white.

When voltage is measured from the three wire line (black, white, red) voltage is 120 between the black and white, and black and red.

If measured from three wire line to the two wire line voltage is present but much lower about 80-90 volts on an analog volt meter, what gives?

What's the proper or likely proper wiring order?

Please restate your problem. A wire is a single wire. Two or more wires in an outer covering is a cable. You can have 2 wire cables and 3 wire cables (and more). From your description I can't tell which black and which white you are referring to.



Light switch with 2 black, 2 white and one red wire.

If the switch is missing how can you say that has 2 blacks and two white wires and a red wire. You must mean that there are 2 black, 2 white and one red wire in the switch box.

If the fan runs with out the switch installed, that would mean that power is being fed to the ceiling fixture box (for fan/light) with a direct connection of hot and neutral to the fan/light fixture. From the ceiling box, power is being fed to the switch location on the black and white wires of the 3-wire cable. The red would be used to return power through the switch to the light of the fan/light fixture. Power would be fed from the switch location to the outlet by the black and white of the 2 wire cable.

To verify this, connect the black of the 3 wire cable to the red of the 3 wire cable. Turn power on. Light should be on. Next connect the black and white of the 3 wire cable to the black and white of the 2 wire cable. Outlet should work.

If all this checks out, connect the two white wires together with a wire nut. Connect the two black wires together with a wire nut and add a pig tail. A pig tail would be just a short piece of black wire. Next connect the pig tail and the red wire to the switch. Doesn't matter which wire goes under which screw.
