You have to run a new wire to the other 3 way switch. The red tells the other one what position the other switch is in. Of course your switches have to be changed to 3 ways. It is unclear why you would ever have two blacks but only one white wire and where they might lead, and what exactly you’re trying to do.

I recently wrote about overloaded dimmer switches , but the most common problem I find is a dimmer switch connected to a ceiling fan. Standard dimmer switches should never be used to control the fan motor on a ceiling fan because the dimmer could damage the fan motor, or overheat and start a fire. To know whether a dimmer switch is intended for use with a fan, just remove the switch cover; there is typically fine print right on the front of the switch saying whether or not it can be used with a ceiling fan.
The photo below left comes from a fan speed controller — this is what needs to be used on a ceiling fan. A safe repair can be as simple as replacing the dimmer switch with a standard toggle switch, but you also lose the ability to dim the light. If the wiring for a ceiling fan is already in place in your home ie — you have separate wires for the fan control and the light control , it should be fairly easy for a qualified person to wire up separate controls for the fan and the light, which will include the ability to dim the light.
You can actually purchase a device that will do this — it consists of a wireless remote and a receiver that gets wired directly in to the fan. These devices work very well, and as far as I know, they can be used with any ceiling fan.

If you are unfamiliar with wiring, use a qualified electrician. Make sure the power is still off.

On most leds with leads, the longer lead is positive. Leds are current sensitive devices, meaning that if the current flow through the led isnt limited, the led will burn out. Usually this is prevented by using a resistor to limit the current thru the led. Leds are also sensitive to polarity, meaning the correct wire must be on the positive and the correct wire on the negaive lead of the led or it wont work.
Dec 18, · The blue wire (black/blue) goes from the H terminal on the headlight switch, this is what gives power to the headlights, but the power goes thru the dimmer switch. Tan is the wire out of the dimmer switch that connects to the low beam terminals on the bulbs.
Colors are shown consistent with the NEC. Before reading this page, you may want to visit 3-way switches and 4-way switches. Single light circuits Below is perhaps the simplest arrangement, panel to switch to switch to light: Below is a variation with the light between the two switches, i. In this case, the end of the white wire from the light box to the right switch must be re-marked black to indicate that it is a hot wire: Next is a circuit with the light between the two switches, but with the panel feeding the light box.
Note similar remarking to above. Controlling More than one light Any of the above can be modified to control multiple lights. Additional lights are just wired in parallel with the first, using two conductor cable. The black should be connected to the black wire feeding the light and the white to the white wire feeding the light in all cases. Here is one example. Here is a rather different arrangement that requires 3-conductor cable between lights:

Are you sure that you want to delete this answer? Yes Sorry, something has gone wrong. My first response would be to call an electrician or somebody familiar with electricity. If you decide to not do that, here’s what you do. First get a voltmeter. Then you’re going to make sure the uninsulated conductors copper part of the wire are not touching anything, and turn the breaker on.
Yes, but you need special 2-way dimmer switches.
This makes and breaks a magnetic circuit each time a spark plug fires. Because of the high HEI voltage 35, volts , special 8mm diameter spark plug wires with silicone insulation are used. Silicone insulation is soft and must be handled with extreme care. Replace any scratched or nicked wire. Fuel economy is improved at cruising speeds and exhaust emissions are reduced. Restarting of a hot engine is improved. Figure shows the different ESS operating modes. Figure – Electronic Spark Selection operating modes There is no change in engine timing during normal city driving.
This decreases catalytic converter warm-up time and reduces emissions. When starting engine, the spark is retarded from normal advance on all cars.

Installing a three-way dimmer switch on an existing 3-way switch circuit is not only a simple job, but it will add flexibility to your lighting design and improve the overall atmosphere of your living space. The primary thing that confuses most do-it-yourselfers is the fact that only one of the three-way switches needs to be replaced with the dimmer switch. So, your first step is to think about which of the two switches you use the most. This is the one that you should replace with the dimmer.
Turn off the power to the circuit. Remove the cover plate from the switch. Remove the two screws that secure the switch to the wall box and gently pull the switch out. Double check with a voltage tester that the power is off. Position the switch so that the side with the two screws is facing your right. Hold up the 3-way dimmer next to the existing 3-way switch in the same manner. Remove the RED wire from the existing 3-way switch and connect it to the same place on the dimmer switch.
In most wiring applications, the RED is connected to the single screw on the left side of the switch.

Kit Stansley I like mood lighting as much as anyone, particularly first thing in the morning when the full blast of light from a watt bulb makes me scream like a vampire at high noon. Regardless, I like to be able to adjust the brightness in a room, and installing a dimmer switch is a pretty easy way to get control over your lighting. If you have CFL bulbs you will need to go with one of the newer varieties, like those from Lutron.

These switches can often be quite expensive to replace. An inexpensive solution is to wire a simple toggle switch in place of the headlight switch, which generally also controls the driving lights. Toggle switches are available at most auto parts stores as well as electronics retailers, such as Radio Shack, and can usually be wired up without too much trouble. The switch should be close to the old switch’s location so that you can simply run the existing wires to the toggle switch.
Disconnect the wiring harness or wires from the back of the switch. Determine which wires send power to the headlights when the headlight switch is turned on. Consult a workshop manual specific to your car for the wiring diagram if you cannot determine which wires are for the headlights. The back of the toggle switch will have a number of attachment points for wires, which will vary depending on the type of toggle switch you are using.
These may be blade type connections or even screw type connections that use a screw to fasten the wire in place. This will probably require cutting the ends of the wires and fastening a blade connector to each end.
