Q:How do you properly wrap copper wires? We have been using electrical tape and it's melting the tape. This is in a camper, and it's in the electrical box. We're using this tape because the wires kept touching and arcing off of each other...I'm guessing :/

It is not how you wrap the wires. It is how you connect them. You should use wire nuts or wire crimpers or splice joints. The tape is melting 'cause you are getting a loose connection and causing sparks. Once you get the wires tight you should cover the joints with electrical tape to keep the wires from touching any thing that they should not be touching..

Q:I am buying my sister Interior Underdash lights for her car, but it says it requires a quot;hard wire installationbecause it does not come with an on and off switch. What exactly does that mean? Will the lights turn on and off according to whether the car is on or off? Also, what is a hard wire installation?

Hard wire means it's not just plugged in. eg. using the cigarette lighter but instead is permanently wired in. All you need to do is wire the lights ground wire to any ground wire under the dash eg. ignition ground or radio ground ( wire will be black ) or directly to a screw that goes into any metal part of the chassis and wire the lights positive wire to either the accessory wire from your ignition (lights come on when car is on) or a constant power wire eg. radio power wire and wire in a toggle switch so you can turn the lights on or off at will.

Q:I have a 1997 saturn sc2. In the trunk of my car there was a wire dangling down from the top when i bought it. Asked seller and he didnt know. It is not the trunk light wire or has to do with any of the tailights,blinkers,brake lights. It looks like a factory wire. It has a bunch of holes in the connector.

it might be a connector for a cd changer. if it has a factory radio with a cd button, but no in-dash cd slot, that could be what youre lookin at. sounds like a square plug? maybe 10 or 12 holes?

Q:Which is live and which is not, there is a black wire and a blue wire?

The oven is rated at 220 volts they are both hot conductors.

Q:Replaced the old fan in my bathroom (about 10 years old) with a new fan. Trouble is this. The fan and light each work on a seperate bathroom switch. I have two spots to install the wire on the new bathroom fan/light. One for the fan and one for the ligth. However, the wiring has one white, one black, one red and the ground. Anyone know what the red is? Can I just cap it off? According the bathroom fan wiring it says something about connecting red to blue. I am slighty confused. I think it was originally only wired between the white and black. I am not sure if I have to get some extra wire and connect the black and red to the light and the white to the fan? Extra wire is confusing.

the black is one switch leg and the red is the other switch leg connect black to fan and red to light and ground the green or bare wire it will work just fine and connect white to white neutral

Q:I am in the process of installing a new thermostat, but I ran into the problem: new thermostat has 4 ports W, Y, R and G. But the old thermostat has 5 wires: W, Y, G and B. I am not sure where B wire (black color) should go. Do I need to look for another thermostat that has a port for B wire?

The black wire should be for ground. You and try to connect it without the black first to see if everything works ok, if it does tape off the black and tape it to the other wires. If not look at your UPM diagram and see which port is for ground and it should hook up with that wire. But I would double check with the heat pump wiring diagram to see what that black goes to and verify that wire with a multimeter.

Q:Ceiling lights wire guage

It may depend on whether you are connecting to an existing circuit or you are running an entirely new one from your panel. If you are connecting to existing circuitry, then you need to check the breaker size. If it is a 15 amp circuit, then #14 is acceptable. If it is a 20 amp, then you must use at least #12. It is very unlikely that you are required to use #10. NEC does not require it for a 20 amp circuit. If you are running a new circuit, then you have your choice. Just make sure that the breaker sizes and wire sizes match as described above. Contrary to the advice of some, it is just fine to run a 15 amp / #14 circuit for lights. The key is to avoid overloading the circuit. If you are just going to add a couple of fixtures, then the 15 amp will be fine. If you are adding 20 recessed can fixtures, you might consider the 20 amp circuit option. If you think that you are going to add more to the new circuit later, consider that when you decide which size to use. The difference comes in working with the wire. #14 is much easier to bend and work with. I certainly would not attempt to use #10 unless you actually do have some weird local codes that require it.

Q:ok got the mute wire figured out thanks to yahoo answers people..now i was wondering what the [ ILL] WIRE IS FOR ,ILLUMINATOR FOR SOMETHING?..also which wires on the speaker wires are pos and neg one is solid ,one is solid with stripe..not sure which is pos or neg thanks alot steve

ILL wire is for illumination. is for the dimmer wire from your aftermarket harness (enables the radio to dim with the rest of the interior lights when you turn your headlights or parking lights on). this wire is not required to be hooked up for the unit to fully operate as some vehicles may not have the proper 12v dimmer wire. The speaker wires that are solid in color (white, Grey, green, purple) are positive (+) and the wires with a solid color and a stripe is negative (-).

Q:I bought this ceiling lamp, and there are 4 wires coming out of it. One white and one black (positive and negative), a bare copper wire for grounding, but there's also a yellow striped green wire. I was wondering what's the latter one for ?In my ceiling I have the black, white and bare copper wires.I'm Canadian by the way

Bare and Grn Yel. are both grounds . Just connect one or the other to the 'bare' in the box.

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.

I would say you should have a wiring schematic to guide you. You could try searching on line for some free information or buy a shop manual published by Chevrolet. You could try one of the Haynes manuals, but sometimes they are not as complete as the shop manuals. You could also go to a local dealer and speak with someone in the Parts Dept. or speak with a mechanic. If you want to try it yourself, I would have someone hold the key in start position, and measure the voltage on those three wires on the wiring harness. Only one should have voltage when the key is in the start position. This wire has to go to the solenoid. That's the next thing to determine, which one. One is probably a ground and one goes to the coil in the solenoid. With an ohm meter, measure the resistance on these two wires. The one with the most resistance is probably the ground, and the other one is probably the coil. If you connect this wire to the wire we mentioned earlier, you will probably be OK. After this point, I don't think you could hurt anything. If you try it and it won't work, switch wires. Good luck.
