Q:Ceiling light junction box has 2 wires (black and white on both). One of the two is hot (always juiced). The other of the two travels down the wall to the switch junction box, and this is the only wire in this junction box. When I connect the two blacks and the two whites of the ceiling junction box, the switch wires become juiced. But when I try to hook up a switch to those switch wires, the switch doesn't cut the power to the ceiling junction box when I flip the switch on and off. Why?? -very frustrated.

You should check your building code in your area even though 12/2 is the most common allowed wire for homes some juridictions require 10/2 which is a larger gage wire. If you do not use what is code than if it causes a fire your insurance may not pay due to you usse a wire that is not up to code

Q:I attempted to change a bathroom fan to a new one with the help of a friend. He disconnected all the wiring without paying attention to what he was doing and what was wired where. We have a set of wires coming from somewhere (I presume the fuse box) to the fan that is hot regardless of the switch being on or off. That has a black, white and naked wire in it. Then we have another wire that comes from the switch that has black, white and naked as well. The fan has black, white and green. Can someone please tell me how to connect these as we have tried everything and the only thing that works is wired to the constant hot which of course won't allow us to turn the fan off with the switch...

1) Turn off the power. 2) Install the fan completely into desired location. 3) Insert both wires into fan's junction box. 4) Twist the two bare wires together, install crimp sleeve onto them at the twist. 5) Find the green screw and connect ONE of these bare wires under it and tighten it down. 6) Cut the OTHER excess wire and fold all this connection up into the junction box. 7) Take the white wire that is coming from the (I presume the fuse box) , and connect it to the white wire that goes to the fan itself. Strip 1/2 of insulation and twist the wires together, install a wire-nut and fold this into the fan's junction box. 8) Take the black wire that comes from the switch and connect it to the black wire that goes to the fan itself. Strip 1/2 of insulation, twist the wires together, install a wire-nut and fold this into the fan's junction box. 9) All that's left is the black wire that is coming from the (I presume the fuse box) , and the white wire that comes from the switch. Strip 1/2 of insulation, twist the wires together, install a wire-nut. 10) Take a black Sharpie pen and color this connection's white wire black and fold this into the fan's junction box. This is known as a switch-leg. 11) Restore power and test. I will you with these two thoughts: 1) It is always best to hire a pro for this type of work. 2) Good luck and may God bless.

Q:I am trying to test a engine coolant temperature sensor (ECT), and in one of the tests it states quot;connect the terminals of the electrical connector with a jumper wirequot;. Where can I find a jumper wire? Does it has to be an specific gauge or any jumper wire? please helpd

Jumper wire is just any piece of wire that allows you to connect two other wires/terminals whatever. You could probably even use a paperclip if it will fit, just have to be careful when jumpering that you don't let the bare material short to ground.

Q:I am in the middle of changing my thermostat and I am so lost on where the wires go! Anyone who knows anything please help.My old system was labeled and hooked up like this:White Wire (W)Red Wire (R)Blue Wire (B)Green Wire (G)Now I am looking at my new system and these are the spots that I have:(G) (RH)(RC)This has a red wire attached like a jumper wire(Y/O) (W/B) (Y1)What wires do I plug into where? Please re-post with the wire color next to where it should go.

dear, each color line on the wire, must to CHG in joint, cause the element is created by ohm to handle short circuit of fire.

Q:I'm trying to fix a light fixture for a friend. Her father-in-law gummed it up. At the fixture, there are 3 white wires soldered to a single wire. There are 3 black individual wires and one red wire. There are three switches that control the light.If I hook one of the black and the 3 white to the light, the light stays on constantly. If I hook either of the two other black individually, nothing comes on period.I'm pretty much at a loss. Any advice would be greatly appreciated.

Can you post a picture?

How To Identify Neutral Wire

Q:Why is the current limiting circuit used to measure the resistance of wire by voltammetry?

Under normal circumstances (to meet the safety conditions), because the current limiting circuit energy consumption is small, the connection is simple, therefore, priority is given to the current limiting method

Q:i have a 00 gmc yukon and tried installing my cd deck. i pulled off the original harness from the stock deck radio and now its just all wires (its my first so i didnt know), i connect the alpine deck wires and tried to connect them all together. i had a few figure out, except a small noise coming from my stock tweeters every time i step on the pedal. then my speed odometer sensor was going with the bass of my subs... whats wrong? can someone find me a chart of what color wires supposed to go where? thanks for your help

do now no longer combine the speaker outputs out of your head unit. you could harm the final unit this type. you at the instant are no longer harming something via using working a a hundred-watt speaker on a lots cut back powered amplifier (and you will now no longer inevitably boost the sound intense high quality via using switching to a speaker with a cut back skill score). The a hundred-watt score is only the optimal skill it truly is stated for this speaker; it does now no longer propose that it demands that lots skill. in case you pick for extra advantageous skill than your CD deck substances, you will might prefer to function an outdoors amplifier.

Q:I have 2 wires that go from the Solenoid to the wiring harness. But i don't know which wires go to where. One of the wires from the Solenoid it the remote switch and the other is the power for my whole interior. There are red, orange and black wires that come from the wiring harness. but i don't know which ones to use.

Your looking for a drive ,but if you would like to look for a starter try Competition Sales online.They deal with mostly Chevy performance parts. Good luck

Q:the quot;rite-tempthermostat was ripped from the wall, and the brown wire, and red wires - both not labled are disconnected...where do they connect? please help....rite-temp thermostat model 8050c

The Green wire generally is fan The red wires are hot to the AC and Heater The yellow wire is AC The white wire is common. Brown may be used for AC instead of red Hook the Green to the G terminal The Red wire to the Rh terminal The brown wire, I believe is Rc terminal White to W OR c (HOW EVER IT'S LABELED) Yellow to Y
