Help With Wiring: 1 Switch Controlling 2 Lights

Hello. I'm a new home owner and DIY-er. I have 3 fluorescent lights  in my basement. I just replaced the fixtures' older ballasts with new  T8 ballasts in the first two lights and they work fine. I am having  trouble with the third light's wiring to the ceiling. I cut and removed  the old ballast without paying much attention because I was able to wire  the first two lights without any problem. I connected the new ballast  to the bulb sockets in the fixture, just like I did with the first two  lights. When I went to connect the ballast's black and white power lines  to the ceiling lines, I was thrown off by a red wire, which I guess is  connected to the light switch.  In addition, this light is connected to  the one of the other fluorescent lights and both are controlled by the  switch. I have attached  pictures of how I have it wired.



The way I have it wired now,  the other light turns on and works fine when the switch is flipped.  However, this light has the bulb flicker and then not turn on. If anyone  can tell what I'm doing wrong from looking at the pictures, I'd  appreciate any help! Thanks!

I've installed two dimmer switches in the bar area of my basement. It's the dial type, where you can push the dial in to turn the light on or off, or turn the dial to dim the light. One dimmer operates the recessed lights in the ceiling, and the other dimmer switch works a pendant light that I have over my bar. The dimmer for the recessed lights works totally fine. They turn on, off and dim. The pendant lights, on the other hand, only turn on and off. They for some reason will not dim. I checked the voltage on the pendants to see if maybe it was an issue of the switch being a high voltage dimmer operating low voltage pendants, and the pendants are 120V with 75 max wattage. I'm at a stand still. I have no idea what I'm doing wrong. Do any of you have suggestions? I took a couple pictures, not sure what good they'll do. The best I can do for a camera is my iPhone, so they're not the best quality.








      
Hi, I recently moved into a 1954 house with a  20amp electrical system, not the old fuse type, but there are no ground wires.



I removed an old light and replaced it with a light fan combo. As I removed the old light (after turning off the breaker) I noticed from the ceiling that there were 2 white wires tied together with a wire nut and 2 black wires, one attached to the white wire in the light and the other attached to the black one from the light. Feeling this was wrong and should be black to black, white to white, (even knowing full well the light was working fine before I disconnected it) I wired the fan the way I've always wired fan lights,  white to white, blue and black to black.  (again, knowing full well the light was working the other way). Turned breaker on then powered on switch. POP at the switch, breaker switched off. I reworked it back to the way it was before with whites tied off, black to white, black and blue to black, turned it back on and  viola, things worked fine. (I know, duh... Right???)

2 questions from this experience...

1. Why would the 2 whites be tied off with only black wires used?

And 2. It seems that one of the light switches in the same circuit as the blown one is now working soft. In other words, it used to make the normal click noise when turned on/off but now it just moves softly up and down without the click. Could I have damaged something when I mis-wired?
      
I have an outdoor light fixture that I am trying to replace.  The house was built ten years ago.



When I removed the original lamp, I noticed one of the two leads was wired to the ground, and one was wired to the black wire, which is hot per my current sensor.  There are three wires in the box - black, ground (bare copper), and white or neutral, all from a single romex cable.  Unfortunately, I do not recall where the white was when I removed the original. 



I wired the new lamp per the instructions, something I have done many times before - black to black, white to white, and bare copper ground to ground.  Nothing.  The lamp and bulbs are brand new, and I have tried four separate bulbs.  I checked the black and neutral with my current sensor and with the switch on and the lamp installed this way, both show as hot. With the lamp not installed, the switch on, and the wires disconnected only the black shows as hot.  The switch is single pole, and appears to be wired correctly with a black to each screw on one side and a copper ground on the other.



Assuming the new fixture was bad, I reinstalled the old fixture correctly -  black to black, white to white, and bare copper ground to ground.  Still nothing. No light, and I confirmed the bulb is good by putting it in another lamp.   The only way to get it to light is to connect the neutral in the lamp to the bare copper ground.



I capped the wires, turned the circuit back on, and identified all the outlets, switches and fixtures on the same circuit.  I opened every one of them up (four lights and eight outlets) and found three (one switch and two fixtures in another room) where multiple commons connect.  All were properly connected.  My outlet tester shows all outlets as "correct".  I found no instances of grounds connected to commons or vice-versa.



Any ideas?  Is it proper to wire this thing the way I found it?



Thanks for any and all advice!
      
Hi, I have a fluorescent light I'd like to remove and add a tracklight.



Luckily it's in the basement with an unfinished ceiling.



here's the circuit map as is now:



1. breaker to fluorescent light.... connections inside

2. fluorescent light to switch at the top of the stairs

3. switch to the light in the stairwell. This terminates the circuit.



The wiring is all 14/2



I'd like to replace the the fluorescent light with a track light, but I'm not sure how to continue the circuit to the switch in the stairwell.



Is it safe to...



1. bring the cable from the breaker to the junction box.

2. connect the black wire with the black wire on the light AND the black wire leaving the box to the switch in the stairwell using a marette.

3. connect the white wire with the white wire on the light AND the white wire leaving the box to the switch in the stairwell using a marette

4. connecting a 6 inch bare 14 gauge wire to the box ground screw, then using a marette, connecting it with the ground wire from the cable entering the box as well as the one leaving and also the ground wire from the light.



Will this work and is it safe?
      
I'm trying to fix a problem with a track light installment over the a bar I've just put in. I've done it before. never had issues. but this particular problem is driving me nuts. It just defies logic.  The electrician who actually installed the associated dimmer switches with this dining room area was called as it seems it may be a flaw with his wiring, but he's blown us off and I have to try and solve this myself.



This is how it's all set up. I've been rehabbing our home from top to bottom, and converted our old kitchen into a dining area. Within this dining area are four sets of lights, all controlled from one box containing four dimmer switches. I set up all the new wiring and installation of the lights in the ceiling, and we paid an electrician to come in, check everything out, set up the multiple switches, and connect it all to the board. It's all new copper wiring from beginning to end, as I didn't want to connect or splice in to the old aluminum wiring that was in place. All the new wiring and lights are on a dedicated 15 amp breaker. Three of the sets of lights were set up to be available from the day the electrician came around. The fourth, for the track light over the bar, was left hanging from the ceiling capped off and with the switch off, as I still had work to do installing an overhead wine rack, under which the track was going to be set.



Two days ago I finally got around to putting the track up, but after setting it in place and connecting the power up the lights wouldn't work. I took the lights out to our kitchen, where I installed another track light system some time ago, plugged one of the lights in, and it worked just fine. I then went back to the bar area and used a spare track, then a spare connector, to see if I could isolate the fault, yet neither of the items provided a solution. Now here's the weird bit - every time I tried checking the system out, I'd get 120 volts showing from the wiring and from the track when I'd test with the multimeter. But the second I'd put a light into the track, the multimeter would drop to zero on the voltage reading on either the wiring or the track. Take the light fixture back out, and the voltage would pop back up. Inserting the light was thus completing some kind of odd loop. It wasn't just one light - I double checked by grabbing working lights from the kitchen track and inserting them into the other track - the same problem would pop up. Finally, having come to the conclusion that there was nothing wrong with the track at all, I took the whole assembly over to a nearby wall outlet, used some spare electric cable to connect up to the appropriate slots - presto, the light came on! I even double checked all this by grabbing another light fixture destined for our bathroom, and tried connecting it to the wiring over the bar. Nothing. Yet as with the track light, the minute I took it over to the wall outlet and connected it, the light worked.



So everything logically points to the fact it has to be something to do with this individual circuit, right, because a) the light fixtures work when plugged into another circuit and b) the other three dimmers and lights hooked up in the same box work fine and draw power from the same wire cable/breaker combination. The only things left that I can think of is that the electrician has either wired the dimmer switch up incorrectly or that there's some kind of flaw inside the switch itself. Does this make sense?



A friend also told me to double-check to make sure that the black wire feeding power to the light was indeed the hot wire, and it is.  If I touch it with the black test lead from the multimeter and put the red one to the neutral I show 120 volts. If I keep the black test lead on the black wire and put the red test lead to the ground - I also show 120 volts.



A final point. I know I'm not overloading the circuit - not even close. With all four dimmers maxed and every light on - including the test light on the track - I'd only be drawing 8 amps on a 15 amp breaker, besides which I'm only using one set of lights while I'm working on this problem anyway. This is a dedicated circuit, so there's no additional power being drawn away by something else.



So how am I getting 120 volts from this wiring, according to my multimeter, yet it won't light up ANYTHING and keeps giving off the indication that some kind of loop or short is being created every time I actually plug a light into the track? It's got me totally stumped.



Anyone have any ideas?
      
Hello I need seriouse help! In my situation I have a three switch, one for the light, one for the vent fan, and one for the heater. This is in a bathroom rent house. My problem is that when I turn the switch on for the light, the light and fan turn on, when I switch the heater on, that switch does nothing, the same when I switch the fan on. The wall plate is labeled: light, fan, heater. So what I attempted to do is put a switch outlet combo in. I have two black wires, two white wires and a ground. So I put the black wires on brass and the white wires on black,( they are black screws instead of silver, not sure if I got the right kind of switch). So when I did that, when I turn the switch on, the fan turns on, but no light, also when the switch is on the outlet is hot.( which fine that is how I want it). But what did I do wrong, why does fan work but not the light. I my biggest fear is that I might have made a fire hazard. Please help and tell me if what have done is safe, and maybe help me figure out how to turn the fan and light on with the same switch..  Thank you for all your input, have trouble falling asleep, keep thinking the house might burn down.. Sorry for the long post
      
Hello there,



I just installed a new fixture in my dining room. It has 5 MR16 halogen bulbs. When i turn on the light switch, the lights are gradually turning on to full brightness. The process takes a between 5 to 10 seconds.



I removed one of the bulb and noticed it took a bit less time and continued until I had only 3 bulbs and then the lights are turning on instantly.



So I think its obvious that the fixture is drawing too much power from the circuit. My question is, why? What tests can I dk to find the cause? Is it a faulty switch or faulty wiring?



Thank you!
      
I'm wiring two lights to one switch with power coming into the switch. All the diagrams I see show the connection of the two lights at one of the lights(if that makes sense). Can all of the connections be made at the switch box if theres room? Basically a wire from each light and the power wire all run to the switch box and connected.
      
I am going to install some can lights throughout the house soon.  I have one light in the center of each room that is already wired up.  I will be patching the existing light boxes up to run the new can lights, utilizing the wiring that is already present. 



When hooking the extra lights up should I use 12/2 or 14/2 wire for running them in parallel?  There will probably be no more than 3 or 4 can lights per room ran with CFLs.  The current lights that are in each room take up to 3 bulbs per fixture.
      
I am only using a simple "non-contact" voltage detector. I am getting a reading from the switch, along part of the line and then at the lights themselves, but the lights are not coming on. I have not gotten into the attic yet to check the line and junction box. What could cause this? An open connection or loose connection? Any help with troubleshooting would be great.



This is a new install of lights, they were not existing. Power is at the switch. Had single pole now I have a double switch. (the existing light that was on the single pole is still working fine). At one  point I connected just the new lights to the existing power, single pole switch, and still did not have lights.
