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:Im replacing the factory rear speakers in my car but cant figure on which wires are positive and which are negative. I went on a site for impalas but the color wires they have listed are not the same color wires in my car your help will be appreciated.

your positive is always going to be the lighter color or the one with the stripe running down it

Q:Which of the following wires would tend to have the least amount of electrical resistance? a) long b) fiberglass c) hot d) thick

thick wires have less resistance

Q:In that chart it has 2 sections, one is maximum amps for chassis wiring and the other is maximum amps for power transmission. What is considered chassis wiring and what is considered power transmission?

brake hp is the power at the 'crank' (the power the motor produces). rwhp rear wheel horsepower is the amount of power actually achieved at the wheels which is usually much less because the power is transferred from the transmission and drivetrain.

Q:i have a purple wire i have no clue what it goes to, i have a dark blue/brown wire i dont know what it goes to and want to make sure the i just cap off the orange wire…Can someone please help me-it is draining my battery

The limited Information you provided makes it difficult but I am going to assume that you are/have put in an aftermarket stereo. The purple (violet with yellow stripe) wire goes to the PCI bus and is not used with aftermarket radios. Cap it. The orange wire is to dim the radio display when the headlights are on. Optional but not required. Cap it. The dark blue with brown stripe is not in the wiring diagram for the radio. The right front speaker wires are Violet/Dark Green stripe and Dark Blue/Red stripe. If your battery is draining then make sure the Red/White stripe wire is connected to switched power and the Pink wire is hot all the time. If reversed the battery will be drained.

Q:How do I connect a speaker wire with four wires (white, black, red, and green) to the back of speakers with only two connections (red and white)?

Don't quite understand what you are trying to do. Speakers only require 2 wire for connection a positive and negative (usually in red and white or black). Receivers only have 2 wires per speakers a positive and a negative (usually in red and white or black). Your cable has four wires in red, white, black and green, you use only two wires per speaker in either combination of colors. This cable is designed to have 2 set of speakers, the left and right.

Q:where can i buy these type of wires (copper insulated wires)??

Any hardware store or Lowes, Home depot There's nothing special about Insulated wire, but what size wire ? What's your application ?

Q:I have a 1989 Nissan 240sx. Somehow the fan caught a hold of the wiring harness and tore all the wires. any idea how much it's going to cost?

Depending on how many wires were damaged and need repaired, I wouldn't recommend a repair unless you can solder them and heat shrink them. And you would want to stagger the joints so they are not all in the same place. Getting a used wiring harness shouldn't cost much. Probably the same as getting all the tools necessary to repair them. (if you don't already have them.) then all you have to do is run the new one along the old one and unplug connectors one at a time.

Q:I recently instaled a Alpine in dash dvd player, the only wire i have left is the safety wire that needs to go to the parking brake wires. Where can the parking brake wires be found on a Ford Explorer and which 1 shound it go to ??? Thanks in advance!

these guys dont know what they are talking about, I just did this last week. First off when you step on the parking brake it connects a ground loop, thats why you connect this wire to ground NOT 12VDC(youll fry your deck). If your deck has no special sequence of the parking brake going off, then on, then off, then on then go ahead and permanently ground the wire. If there is a sequence mentioned in the manual, you need to install a toggle switch, and connet one side of the toggle to ground and the other side of the toggle to the parking brake wire on the deck. Most decks have a sequence you must follow, for my dual brand dvd player you must flip the switch on, off, on and wait 3 seconds. presto it works while driving. Also illegal in most states. Happy hunting

Q:What's the thickness, or measurement for the last or thickest wire?

they change your wire according to how much your teeth have shifted around, so it just depends. the ortho needs to adjust the size of the wire due to your teeth straightening out and making sure the wire(s) are at a correct length. its really not that thick of a wire, so don't worry about it. :D
