Question

Thanks for your answer. I don’t see how I can do this since there is only one black wire that comes from(or to) the switch to the fixture. There are no more reds. There are 3 black wire, 3 white and one red in the ceiling by that fixture.

Thank you for your answer.

One red and one black wire comes from the switch.Wheh I put the black that turns on #3 fixture with any single black wire, then the respective fixture goes on. However, the red does not seem to do anything. As I said before, I even put the red with the whites any nothing changed. Putting any 2 blacks together does not do anything unless it is the one that feeds #3. Could there be a short in the red wire. It would seem that the red would be the switch wire but the switch does not work and I even bought a new switch and that did not make the light go on and off. It just stays on.

Thanks again.

Question -

I changed 4 ceiling light fixtures. One of the had some wires that twisted off when I changed the fixture and thus did not know which wire went to which wire. 2 of the fixtures went up fine. I will call these the number one and 2 fixtures. The # 3 fixture is the one that had the wires twisted off. The #4 is above the kitchen sink. I got the # 4 to work also. There are 3 white wires and 3 black wires and 1 red wire and 1 short «jumper»» wire in the #3 fixture that the wires twisted off. The problem is that the # 3 fixture will just stay on if the switch is on or off. It will not turn off. I changed the switch and it just stays on. I know that one black wire goes to the #4 fixture above the sink. One black wire goes to the kitchen stove fan and light and the other black wire goes to the #3 fixture. I have tried to wire these different ways but the light will just stay on. I put the white wires(3) together. I have put the red wire with the black wires and also with the white wires and the light will not turn off.

I know one black goes to the fan/light, one goes to the sink light and the last one goes to the one it is connected with # 3 fixture. If I do not connect that one, the light will not go on at all. Where would the red wire go? Do 2 whites go together and the remaining white goes with the red?

Before, I separated the other wires and just connected the one black wire to #3. When I did that neither the fan or the light above the sink went on. Those only worked when I connected all the black together and all the white together with a red wire joined witheither the black or white wires. If I did not connect the red to either one, then the fixture would not work. Originally, they had a short white wire but I do not know how they hooked that up unless they had 2 bunches of white i=wires joined by the short white wire. It sounds like you are saying that I should have one white wire connected by wire nut to one white wire in the ceiling(the one that comes from switch. Also, 2 black or one black and one red from ceiling connected by wire nut to black wire on the fixture itself. The thing is that I have tried just about every assortment and it seems that all the black have to be together or else either # 3, #4 or fan will not get juice depending on what wire is not included.

Thanks for helping.

Sorry this has taken so long. I am still a man short on a three man crew. We may have to do some experimenting, as you have already done. I am assuming all the white wires are neutrals since you have aleady connected them all together and did not trip a breaker. You may have to pull the switch to see what color wires are on the switch. I am betting the red is one of the switch wires. One fixture wire will be a neutral. This may have been the short jumper wire. Attach it to the silver fixture screw or if there is a white fixture wire, connect the three whites and the fixture neutral together. As we experiment, do not change any of the neutral or white wires. With three blacks and a red, one will be going on to the 4th fixture, one will be going on to the fan/light, one to the 3rd fixture and the last also to the 3rd fixture to continue on to the 4th light. Disconnect all three blacks and the red wire. Since there is a red wire, connect one black at a time to the red wire until you make the light/fan operate without affecting the other lights or the switch. If this does not work, attach one black at a time to another black until you find the combination of two wires that will make the light/fan operate correctly. This should cure the light/fan circuit. That will eliminate two wires. Now with the two other wires, connect both to the third fixture brass screw and this will connect the light to the circuit and continue it on to the fourth light. Let me know what you determine. Thanks, J

Answer -

Turn the circuit off and remove both wires from the switch. Turn it back on and see if either the red or black wires are hot and let me know. Thanks

Answer -

That should make it easy. The red wire will be the wire going from fixture to fixture to operate the lights only. Start at the first fixture and attach the black fixture wire to the red incoming from the switch and also to the red going to the next fixture and do this on all the lights. The last light should only have one red as it will be the end of the line and no other wires but the one red will connect to it. After connecting all this way if the switch does not operate correctly, remove the switch and attach the red and black on the switch together and this will be a test for the switch. Thanks and let me know, J

Answer

I misunderstood the other wires. The black going to the switch must remain hot and not be connected to the fixture. The red will be the switch leg to go to the fixture black wire and one of the other black wires will be feeding towards the other fixtures. You will have to determine by process of elimination by taking one black wire at a time and connect it to the next fixture which black it is. The same will be for the rest of the fixtures. Once you determine the correct wire feeding from the first to the second, connect one of the other black wires the next light downstream and leave the others loose and connect one black at a time to the second fixture until you determine which one feeds to the lights.
