Q:my radio was stolen i'm trying to put in a old radio in but when someone stoled my radio they cut the wires so now i can't tell what go,s where can someone please help? it's a ford f150 pu trck w/ 4 speakers i just need the wire color codes to hook-up,plus thy stole the manal to the trck too. please help.ty

You might have to go to a speaker shop and they have a little wire gadget there which tells them which wires are what. Don't know if you'll have to pay though or not. You might be able to buy one yourself.

Q:i just got two new aiwa stereo speaker's they come with their own wiring in the back but i dont know which wire is whatthere is one black wireand there is another black with gray dashesim thinking the one with dashes is positive?the speaker works both ways

Chances are the marked wire is positive. For your purposes it doesn't matter a whole lot. The phasing (which DOES matter) will be correct as long as you are consistent with both speakers. If you can remove the front grill or otherwise see the speaker cone directly, you can check the polarity with a AA or other 1-1/2 volt battery. The cone will move forward when the positive wire is *briefly* touched to the positive terminal of the battery while the negative wire is held on the negative terminal. If you see it move back, you've connected the wires in reverse. Don

Q:I just learned how to do 3-way wiring, so that I can turn a light off from 2 different switches. My question is, how do I add another light to that mix, so that both lights come on/go off at the same time when I turn the switches on and off? (It's for a closet that has 2 lights in it that I want to come on/go off at the same time).

You have to tie the wires that go to the light together. It is called parallel.

Q:Question about the 3.5mm cable, I cut it open and there are 4 individual wires inside of it. I've only ever seen 2 wires and a loose one. Which ones are right/left and would the other 2 both be ground?The colors are red/green/white/black. I'm assuming the red/white are right left like normal? But I'm not too sure.

General audio wire color standards: White/Black are ground. Red is Right+ and Green is left+. There are separate wires needed for headphones, and often the ground wire breaks causing the wire to otherwise completely fail. Mono is left only (the tip) + Ground. The wire can usually be replaced with standard 4 wire phone (16-18 Ga) cable, when used for headphone (low power) applications.

Q:wires have been cut and i have 4 wires i dont know what do.what colors are for what?

If your trying to wire a aftermarket radio into your car just go to best buy or any other car audio dealer and buy a wiring harness. It plugs directly into your stock wiring harness and on the opposite side has the correct colors of your aftermarket harness that came with the deck. All you have to do is color match and crimp.

Q:Okay I bought a new light for outside my home. I called the electrician, he got the wiring from the ground and we added cement so we would bolt down the light. Now i need help adding a photocontrol.

no offence and no help but WHY did you not take a note of the connections as others have been told to do,in reality it makes no difference what colour of wiring goes where it is what the wire does that is important in other words if you swap the brown and blue at a light it will still work can you not remember what the connections were at onset of job.Best plan of action when dealing with electrics is if you do not know what to do do not do it

Q:OK, so pretty much this is where im at, I clipped the connector off the wires that went into my stock stereo and now have the wires from my new deck and pretty sure I just have to connect them. Is there A good diagram or tell me what goes to what here.... I'm a bit lost. Its to late to buy a wiring harness seeing as I clipped off the connector... so I dont need to here how I should buy a wiring harness. Thanks

Q:I am installing a GFCI outlet in the kitchen (20 AMP) the box that it is already installed in has more than nine wires running into it. What I need to know is how does one determine the load wires from line wires when there are multiple wires running to an outlet box?

if you have three romex wires coming to the box (which isn't uncommon) then each has a white, black, and bare copper ground. if you have 4 concuctor wires then there will also be a red wire too, 4 conductor wires are used to run to ceiling lights so you can use one wire but feed 2 switches like separate control for ceiling fan and light or vent fan and light for bathrooms. to determine the line vs load wires you need to take note of how everything is connected and write it down, then disconnect the wires and use a volt meter to see which black wires have power. once you do this follow it back to where you see the outer sheeting covering all three wires (white, black, and bare copper ground) in that romex wire and this is your power supply in. the rest are your load wires. as noted you should have some electrical experience to be doing this because if things aren't connected correctly it can be a fire hazard. in your case if all you are doing is swapping out a regular outlet for a gfi then its easy because all white and copper wires are common connections and connected to each other so just connect your GFI as the other outlet was connected with black as your load side and connect the ground wire to it. if you are trying to put in a gfi to also protect the rest of the outlets on that line then determine the black that has power and that goes to your load side and the rest of the blacks are fed from the load side terminal controlled through the breaker

Q:Are those coils of wires in an electric fan magnetic?

Electric motors, all electric motors, have some form of stator and some form of rotor. The rotor is the section that rotates... duh. The stator is the part that houses the rotor and does not move. AC electric motors, like your fan motors, take advantage of the fact that the phases of current alternate through the wraped wires around both the stator and the rotor. The wire wrappings make the rotor and stator into electro magnets. By careful placement of the rotor and stator wires, the magnetic fluxes that surround both parts can be made to alternately pull and push on the rotor. And that causes the rotor to turn. While most if not all commercial motors have wire wrapped rotors and stators so they are electro magnets, some lab motors may have permanent magnets embedded in their rotors in lieu of the wrapped wires. These are way cheaper, but they are typically way weaker than comparable motors with electro magnetic rotors. So, yes, the coils are electro magnets. As long as there is current alternating through them, there will be corresponding magnetic fields and appropriate forces to turn the rotors.

Q:4.A uniform semicircular sign 1.00 m in diameter and a weight of 325 N is supported by two wires. What is the tension in each of wires supporting the sign?

Assuming the wires are vertical, connected evenly to the sign, and that nothing else is supporting the sign, then each wire carries half of the weight. T = 325 / 2 = 162.5N
