Were do you connect the dimmer wire?

There should be two wires coming from the dimmer switch unless it is a 3-way dimmer. The wires should be labled line and load on a normal 2-way switch. The line load is connected to the incoming power wire. the load wire is then connected to the wire that goes to the fixture. If you area replacing an old two way switch, then it will hook up exactly the same as the original switch, except for the fact that you will have to connect the pigtail wires of the switch to the other wires that used to be under screw terminals. I hope this answered your question. Thanks, Ben M. There should be two wires coming from the dimmer switch unless it is a 3-way dimmer.

How do you wire a 3-way dimmer switch that has two red wires and one black and one green when the box has two red and two black?

you can only have one dimmer, the other switch needs to be not a dimmer. the green wire is ground, it connects to a bare copper wire found in the box, or to the box itself, if the box is metal. the black wire is"common" it either connects to the wire found in the box that has power in it or to the black wire that goes to the light. the 2 red wires are"travelers" they connect to the wires found in the box that go from switch to switch. if you don't know how to check which wire does what( continuity), it is possible to keep changinging the connections until the switch works. you will want to do this with a conventional switch, and install the dimmer afer you identify what wires are travelers and wich are common. you will destroy a dimmer switch by searching for the right connection. once you have identified the common wires, it will be on the black screw of a 3way switch; you can put that wire on the black wire of the dimmer. one red goes on one traveler, the other on another traveler. there might be a white wire in the box, if it is connected to other white wires and not to the switch, leave it alone. if a single white wire is connected to old switch, it may be a traveler.you will connect a red dimmer wire to this. opening the other switch location will show you if the white wire is used as a traveler.the black wire has to be either power coming in, or the wire going to the light. the reds are just connecting the 2 switches.


How do you replace a dimmer light switch with a regular light switch coming off of a wall plug ive got 2 black wires 2 white wires 2 grounds and one red wire going to the light?

This is a relatively simple wiring job. Remember that all a switch is, is a means of interrupting the power coming from source (electrical panel) and travelling to load (light fixture). Without the switch, the light would stay on constantly. The black wire is a power wire and so is the red. The white wire is a neutral wire, and the green wire is the ground. You may have to do some trial and error to get it right as I can't see the actual wiring diagram you have. After shutting power off to that circuit, disconnect the dimmer switch and remove. Connect the two white wires together with a wire connector. Connect the two green wires. The red wire was probably part of the dimmer switch and should now be gone, but if it isn't then just cap it off. Now connect the black wire from the fixture to one of the terminals on the switch, and connect the black wire from the electrical panel to the remaining terminal on the switch. That's it.


How do you install a doorbell with four wires both having black and red wires?

It depends on what the wires are connected to and where the power supply is located. If the switch is lighted power has to get to the switch for the light. With a lighted switch you have a hot supply side, a neutral and then the wire going to the bell. So if Black 1 and Red 1 are supply voltage you would connect Red 1 to the hot side of switch, Black 1 would go to common as would Black 2. Red 2 would go to Bell side of the switch.

How do you install a dimmer switch for multi fixtures where the original switch has 2 black wires and one red with no green?

This simple if you have two switches controlling a set of light you will need to buy a three way switch. A three way switch will have a place for three connection. Depending on what brand of switch you purchase the directions will be sightly different but most dimmer come with detailed directions and diagrams. When you by a dimmer you need to read what kind of load it is meant to control. They are built to control incandescent light, magnet low voltage lights or electronic lights.

Ho to Replace dimmer switch 1989 Chevy Celebrity?

The dimmer switch on a Chevy Celebrity is mounted to the steering column, down from the ignition switch. To get to it you will need to lower the steering column. 1. Remove the under dash panel. Make note of how it comes off so you can put it back. 2. Remove the trim panel under the steering column. If you have a trunk release unplug the wires. 3. Take out the four bolts that hold the steering column in place, removal of the steering wheel is not necessary. Let it rest on the seat. 4. The dimmer switch is operated by a rod going up to the turn signal stalk. Take note of how it is attached. 5. Unplug the wire from the dimmer switch. 6. Remove the screws and take off the switch. If the replacement switch comes with any further instructions follow them. Reverse the steps to put it all back together.
