How do you detect a bad dimmer switch?

How do you install a rheostat instead of a light switch?

A rheostat is an extremely ancient form of variable resistor that was used very largely to vary voltage. As you mention replacing a light switch, presumably you want to install a dimmer? If so, lighting dimmers are solid state and are a simple replacement for a standard switch. NOTE - you cannot use a conventional dimmer on anything but standard incandescent lamps. They will not work on low volt, fluorescent or halogen lamps (or HID). Make sure that the circuit breaker is turned off before starting work on changing the switch out. Just for the sake of convention the top wire on your conventional switch should be the hot one. Connect this same wire to the top wire that is on your new dimmer switch. Make sure that the dimmer switch is in the off position before turning the breaker back on.


How do you wire a dimmer with black and green wires to black and white wires?

Answer for USA, Canada and countries running a 60 Hz supply service.If this is a replacement from an existing wall switch to a new dimmer switch to replace the old wall switch, this is what you need to do. The two wires that were connected to the switch are removed and reconnected to the new dimmer. Don't worry about the white wire as it is not a neutral in this occasion. The white wire is a switch leg and as such it should have been identified by a piece of black tape wrapped around it to identify it as a current carrying conductor. The green wire from the dimmer switch is a ground and is connected to the ground terminal in the switch box.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


What happens when you attache the wrong wires on a light fixture?

There is the active the neutral and the earth. if you use the earth as one of the wires that connect to the light it wont work. however the light will work regardless of which way around you put the other two wires.


Why do you have 120 volt in your light fixtures with the switch off?

Under normal circumstances there are three options that it could be. (1) Someone junctioned a circuit that has nothing to do with the light in the light box, (2) It is a wiring method called a switch leg, it is used to reduce the number of conductors at a switch location or when a light was put in old work or (3) Someone installed a switch incorrectly and is switching the neutral conductor. Your best bet if you are trying to work on the light is to just turn the breaker off. If you are confused or do not feel comfortable as to how it is wired contact a qualified electrician to take a look at it, as always safety comes first.

Why don't the headlights work on your 1995 ford ranger?

AnswerIf the lights work on the flash to pass but do not work otherwise either the switch is bad or the dimmer switch is bad. I just am working on a 1995 Ranger and found the dimmer switch to be bad. I checked the headlight switch and that was good so I found the dimmer switch to be the problem. I jumped the wires after unplugging the dimmer switch and lights come on. Replace the headlight dimmer switch and good to go! Hope this helps.


Why did your halogen lamp stop working when plugged into a dimmer switch on a cord?

It was not designed to be used with a dimmer switch. You must have a halogen designed for use with a dimmer or it will not work.
