Q:I live in a condo and Im trying to wire a new light. When I wire it, it stays on constantly despite hitting the switch.The wiring Im dealing with is as follows.At the switch on the wall, there is a red wire, brown wire connected to the switch. A green wire connected to the box in the walll behind the switch.In the ceiling there is a brown wire, green wire, and a white wire wrapped with an unstripped red wire.Coming from the fixture are black, white, green.Ive tried connected black-brown, white-white green-green but the light stays on no matter what. Also tried white-brown, black-white, green to bolt. Still the same thing happens.Not sure what to do.

the red and brown are probably positive (red) and the brown (neg) The green is probably a ground wire. You can go to the hardware store. Home Depot or Sears or Ace etc and get a small tester and then touch it to the wires. It will come with instructions and you can also ask the sales person in the electrical dept.

Q:What Spark Plugs and Wires would optimize my MPG? 2000 Bonneville SSEI

AC Delco plugs wires. Using substandard low end aftermarket cheap junk doesnt help your vehicle at all also replacing spark plugs wires really doesnt improve your MPG unless its misfiring badly

Q:i have a purple wire i have no clue what it goes to, i have a dark blue/brown wire i dont know what it goes to and want to make sure the i just cap off the orange wire…Can someone please help me-it is draining my battery

Q:The black wire is called ground but what is the red wire called?

In single phase AC circuits it's hot (ungrounded). In three phase AC circuits it's A phase. In DC circuits it's positive.

Q:I have an old house and am replacing a dimmer switch in the kitchen.The old switch is has only 2 wires coming out of the switch that are both black. From the wall 2 wires connect to the 2 black wires on the switch, one is black which I have concluded is hot and the other is red, which must be the common wire. My question is that there is a 3rd wired that is pushed into the electrical box that is capped and not being used. This wire is white. I can only assume that would be a ground wire, but why would it be white in color. Can you tell me what the coloring scheme was for wiring old houses? Now I can connect the switch and use only the black and red wire, but would like to ground it properly if possible.

To begin with, don't worry about the white wires tied together in the back of the switch box, that's normal to see in a switch box (outlet boxes are a whole different ball game). The only purpose of a switch (regular or dimmer) is to control the hot (black) side of the circuit that powers the light (or fan or whatever it is). To simplify this for you, just connect one black wire from the switch to the black wire in the box and the other black wire from the switch to the red wire in the box. That will make the connection and your light will work on the dimmer. If there is a green wire on the dimmer switch, connect that to the bare copper wire inside the box. If no green wire, then just screwing the switch to the box will ground it assuming it's a metal box. The metal box should already be properly grounded, you might see a bare copper wire screwed around a terminal inside the box. If the white wire is by itself (or tied in with other white wires) with a wire nut (cap) on it, don't worry about it and don't let it confuse you, it's just an extra wire that's not needed for the switch to work. The only case of where you'll see a white wire connected to a switch is if 14-2 wire was used instead of 14-3 wire (like in your case). 14-2 has a black, white, and bare copper wire. 14-3 has a black, red, white, and bare copper wire. The 14 just means the gauge (thickness) of the wire. And to confuse you even more, another case of seeing a red wire connected to a switch is if the circuit is a 3-way circuit whereas there are 2 or more switches controlling the same light. In your case though, I'm assuming this dimmer switch is the *only* switch controlling your light given your description. Keep in mind, YouTube is a great source for tutorials on doing electrical work if you need it. Just remember to kill the power to the circuit you're working on. Anyway, hope this helps, and good luck.

Q:I have a set of pilot wi-200 strobe lights and they have three wires and i want to hook them up to a optx headlight strobe control module the wires are gray white and black can you tell me where to hook them

I wouldn't try it. The gray, white, and black wires are the high voltage strobe wires. The control module changes the patterns before the voltage is increased. There is nothing you can do here.

Q:how we can predict the maximum load that stainless steel cable wire can achieved?

The specifications are on the spool.

Q:In the ceiling is one black, one white and a ground. How do I connect a new ceiling fan to these two wires? The ceiling fan has black wire, white wire, a blue wire and a green wire. We don't have green in the ceiling nor do we have a ground...knob and tube perhaps? So, can we connect this fan or not?Thanks!

balck to black and white to white...the green wire is the ground wire and the blue wire is for the lights if your fan has lights...hook the blue wire to the black to get power for lights

Q:pendant wiring hookup. issue: light is always on house wires: red, white, black, ground pendant wires: green, white, black (and a ground wire to the frame) I did connect red to green, white to white, black to black, ground to ground is connecting the red to green the problem causing the light to be always on? do I just disconnect the red to green to fix?

First of all you need to determine where the switch that controls the box on the ceiling is. It sounds to me as though three conductor wire was used in the event that a ceiling fan might be installed at some future date. Turn off the breaker to that circuit first. Make sure it is off with a circuit tester. Remove the plate from the switch location and unscrew and pull out the switch. There will be a pair of wires ( white black and bare ground ) coming in to the box. This is where power is coming from. There will also be a trio of wires ( black, red and white plus bare ground. Which ever wire from the trio is attached to the switch will determine which hot wire to connect to in the ceiling box. You will attach that to the black wire from the fixture, the white to white and the green to bare ground. If there are two switches in the same box on the wall, choose the one closest to the door, determine wire color, cap the other color wire in the ceiling box with a wire nut and some electrical tape around it. Push it up in to the box first before any of the other wires. Then make the other connections, attach the pendant base to the ceiling box and you're done.
