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:Suppose we have a 10v battery.one end of the battery is at 10V electric potential and other is at 0V Hence,the potential difference is 10V.if we measure the voltage( p.d.) across positive terminal at 10V and the middle of the wire connecting both ends of battery will it be less??I mean,at the middle of the wire the electric will not be zero,right??(correct me if am wrong)Thanks!!

You are right.

Q:Why do two parallel wires carrying currents in opposite directions repel each other?

since both the current carrying wires produce magnetic fields in the same direction which can be found out by using Flemming's right hand thumb rule the two wires repel.

Q:I was looking at the wiring of my current thermostat and I want to know why it's wired the way it is...The yellow wire was wrapped around the white terminal and the yellow terminal. And the white wire was wrapped the around the Orange terminal. The red and green wires were each wrapped around their respective terminals. And the blue wire wasn't connected to anything. Why would the electrician have wrapped the yellow wire around 2 terminals? Is that normal? Also, I tried installing a new thermostat but the heating is not working. The fan works but it just blows room temperature air. The new thermostat only had 4 terminals for R, Y, W, G. I connected the wires I had to their respective terminals. However, I think it may not be working because I have a probably have a heat pump. Any Ideas why else it might not be working? Thanks a lot!

Yeah it sounds like you have a heat pump and it is wired VERY basically. Your new thermostat will not work because it has no O terminal. You will have to buy a heat pump t-stat then wire it the same way your old one was and it should work fine. In other words Red to R and Rh if it has one, Green to G, Yellow to Y *AND* W, and White to O. Basically what's being done the way your old t-stat was wired is the compressor is being brought on in heat or cool and the white wire on O is switching your reversing valve for cooling mode. The way you have the new one wired is just going to switch the reversing valve and turn the fan on and won't bring the compressor on when the heat is called to run. If your system has backup heat, that extra blue wire could be used to bring the backup heat on if it is re-wired to do so. If your going to have it re-wired I would change the wiring so blue was the reversing valve and white was the backup heat. This would require re-wiring both indoor and outdoor units if it is a split system or re-wiring the package unit if it is that type. Or if you really want it done right have new thermostat wiring run and have it wired properly for a heat pump. If you don't want to go through all of that just buy a heat pump stat and wire it like your old stat.

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

Hi i would be sure to use insulated wires in most situations, the only time bare wires are considered is when there is absolutely no chance of any one touching them and the only time that situation ever occurs is in the case of an antenna for receiving a radio signal. the wire should as high of the ground as possible so no one could touch it.

Q:I have an old house with old wiring. I have no colors to go by.

It should have continuity (low ohms) when tested against the general mass of earth.

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:I just purchased a Pyle Audio aftermarket radio. The wiring is very different actually. It only has 2 single speaker wires (1for each side). So do I hook up multiple wires to one wire or what? I was thinking that I hook up the left front and rear speakers to the left speaker wire and vice versa for the other side. Need some advice.

Wow. I haven't seen a car stereo with that style of wiring in 20 years. Their is no manual online so I am going to assume that it is setup the same as stereos made in the 1980's. You are correct, both left speaker positives go to the left channel wire and the same for the right side. All four speaker negatives go to the ground wire. That means a total of six wires being connected together ( ground from stereo, ground from car, four speaker negatives ).and the red goes to full time battery power. The pics I have seen do not show a yellow memory wire, so you will have to remember to turn the stereo off when you get out of the car. Or it will play til it runs the battery down. Also, you didn't say what kind of car you have, but if it's a modern car with fuel injection and a ECM, I would bet you are going to have ignition noise problems. It's one of the many reasons people stopped using common ground car stereos.

Q:i have old wiring for a stove that iam putting in ,a new box but i have only 3 wires 2 of them are white and 1 black how should i connect on a 4 wire receptacle? on the receptacle 1 white 1 green, 4 a ground then it says x then y ???????

The new 4 wire receptacle needs a 4 wire circuit. It will have a white, a green or bare for ground, and a black and red for x and y.
