Q:I am replacing my garbage disposal. I have black, white wires and a black/yellow wire. How do I connect this black/yellow wire. Is this a hot wire as well?

A wire that is black or red (with or without any other colors) should be considered to be hot (carrying current). Why not just trip the circuit breaker or, at least, turn the switch to the off position before you mess with the wires? Make a diagram of how the wires were connected to the old garbage disposal, and connect them to the new one, the same way. There should be one white wire, on colored wire (not green or bare copper), and one green or plain copper wire. The green or plain copper wire is the ground. That connects to a (usually) green colored screw/bolt that is inside the wiring box on the disposal. The other two wires connect to the white and red/black wire.

Q:I know the ground wire takes unused electricity to the ground but what is the purpose of the neutral wire?

The neutral wire is supposed to be the wire that functions to take the current from the hot side back to the power line. The ground is there as a safety measure - in 3 wire appliances, the ground is usually connected to the housing. It is there in case some part of the hot circuit becomes shorted to the appliance housing - if that happens on a modern 3-wire electrical system, it will cause the breaker to trip. Or, if the appliance is plugged into a ground fault interrupter GFI, that will generally trip first, before the breaker.

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:what wires are my speaker wires going to and coming from the factory amp and how do i hook them up please help i drive a 96' ford exploder

Chilton's guide in the library may have this information. Also, it is online with my library so you might be able to find this out at home.

Q:I spliced the stereo wires to the adapter to plug into my car. there's 2 extra orange wires in the adapter. There orange it says there for illumination and the dimmer. What should I do with them? Did I get the wrong one?

You should have bought a radio adapter for your car! Splicing the cables is not a good idea! You can get a Radio adapter which joins the connector from the radio to the cars radio wiring!

Q:How can it be possible to create a high voltage and have a small gauge wire? Example: 3gj or 3000mw in a small wire (just an example)

The limit on the size of current carrying conductor is the heat produced due to power losses which leads to failure of the conductor, the power losses depends mainly on the square of the current (P=I^2R) so in power transmission voltage is being stepped-up to high values to decrease current and, in turn, the conductor size is reduced. Theoretically we could step-up the voltage to extremely high values and thus we could have a very thin wire to carry the small current because P=VI so at constant power as voltage V increases the current I decreases. But there are also limits for stepping up voltage as the insulation is directly affected by the voltage. In case of insultaed cables, the insulating material (PVC or XLPE) will fail if the voltage reaches its Break-down Voltage. In case of overhead transmission lines (OHTLs) the conductors are insulated by air between phases and the suspended disk insulators each has their own breakdown voltages. It should be noted that safety regulations determine a safe distance of 1 cm per Kv that you should keep from high voltage conductor. This means that for a consductors carries voltage of 500kv you should allow a distance of 5 meters away from it for your safety as its magnetic effect is not exlusive on its surface but for a distance around it proportional with the voltage.

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!

Q:Why do some vehicles have more than one starter wire at the ignition switch?

The extra wire activates the fuel pump while cranking. The run position only lets the fuel pump run if it sees signals from the cam and/or crankshaft sensors.

Q:Can I run a 10 gauge 2 wire plus ground from a double pole 30 amp breaker to a dryer that uses 240v? I need to know if the one black wire will be sufficient or if i need to get a 2 hot one neutral wire.

No you need two hot and a neutral your element needs 240 volts.
