Trying to hook up aftermarket stereo with no factory harness. How can I go about wiring my new stereo wires or my replacement harness (with module) to my car's already existing loose stereo wiring??


Hi Daniel

You need to test & label all the loose wires.

Use a multimeter in Ohms mode to place a tickle of electricity to each speaker wire. you should hear each speaker crackle. (Multimeters only use a 9v battery internally)
Label each pair of wires for speakers.
Their color coding may help. Keep the negative & positive wires to the speakers correct so that the speakers all travel in a forward motion together or you will have distortion from one speaker that is out of phase with the others.
You will also have a permanent +12v line and a Ignition Key +12 volt line.
One keeps the station memory etc when the ignition key is off.

Cheers

Just isn't functioning correctly all together. It will not eject CDs, flip screen, attention, until I reset it a few times, even then only works temporarily!


Pull battery cable off and then go behind the radio and add 1 more wire to the green ground wire to ground in two spots instead of one. JVC is known for bad grounds and no continuity in ground wire. Put on cable on battery. And reset radio and you should being up and rocking. If not hit me back and I will give you more tech support.

Hunter Fan Mod 21617-001, wire colors Black with white stripe/ Pink/Yellow/Red/Gray/Black/White. This has a floresent light, no chains or switches. The Pink serves the light. Note the wires are not labeled...


Red and white are twisted together,or however you combine wires.I use plastic wirenuts.Always twist clockwise as the wirenuts are most effective that way and the wires will stay together better.Black/white,yellow,and gray are the speeds yes,and the fan wires go to the receiver wires.It sounds like you do not have the receiver?If it isn't already built in,it should be small enough to fit within the smallest part of the fan base.The remote is the transmitter.Here is a link to show you the wiring.Red&white twist together for house power.Black for house ground.It also shows a THIN WHITE wire for the antenna.It is not necessary to hang it outside of the casing.You should make it spread out around the inside in a full circle,that should be fine.Just not wrapped tightly around the motor,loosely is better.It does show the antenna wire hanging out in the diagram.You can do that also,just make sure it isn't hit by the fan,and it will not cause a fire if pinched by the plate.If you do have all the wires connected,it shows that the dip switches on the receiver must match.Make sure the remote has the battery removed when changing these.When they are correct,there is no way to tell what the fan is set to and it could start moving.The dip switches are equivelant to radio stations.If you want 101.9FM,but it is set to 101.1FM,it won't come in.When the switches match,you are tuned in and hear 101.9FM.If you need more help,just comment here and I will get an autolink to your post and reply ASAP.Good luck,Greg The link looks universal for Hunter fans,all wired the same.

In order to get my reddy heater to fire I have rock the on off swith several times or the wires on the switch could I havea bad switch


Based off of what your telling me, you could have a bad switch, but you also said you had to shake the wires so I would check all your wire connections to the switch and wherever else they connect to make sure you don't have a loose connection. If all the wiring checks out you can replace the switch (Note:If your reddy heater has a plug unplug it, then connect the two wires that went to the switch together. Then plug in the heater and see if it runs, this will tell you if it is the switch).

Presario 6000 desktop wont power up after transporting. Opened cover & I have loose wires that may be the problem. The loose wires are labeled p9 &p7.


Unfortunately, I do not know P9 and P7. Can you tell me if they are multiple colored wires going into a header/connector? If they are single wires or thin wires you may be able to look at your header of wires which connect the pwr button, rst switch, power led, speaker ( 4 pin thin connector ) if p9 and p7 came off here they could be your power switch.

How do you replace a computer board on a Maytag neptune dryer?


You should get the manual but you can do without it. Take the top panel apart, there are a few screws and inside you'll see the board, remove all wires, make sure you label them so you plug them back in correctly when you put the new board in. Put back together in reverse order of removing and you should be fine.

How do I replace the power supply?


To install a new power supply, you don't have to send your computer to a specialist; you can install one yourself.
Before You Purchase. You can buy a new power supply from your computer's manufacturer, a computer store, or an independent manufacturer, but first you should examine your current power supply. Check to see if your power supply is AT (Advanced Technology) or ATX (Advanced Technology Extended) style. Your power supply should be labeled AT or ATX, and in the same area, you should see the output voltage in watts (for instance, ATX-250W). Be sure to buy a new power supply with the same or higher wattage as your old power supply. The higher the wattage, the more energy your power supply will provide to your computer. If you're adding additional components to your PC, you should purchase a higher wattage power supply. Furthermore, measure the dimensions of your old power supply, and make sure these measurements are the same as the new power supply you're going to purchase.

Get Started. To replace your old power supply, you'll need a Phillips or flathead screwdriver, a well-lit, low-static area (avoid carpeted areas), small containers (to hold screws or loose parts), and a pen and paper.

Turn off your computer and all the peripherals (such as your monitor, printer, modem, and scanner). Unplug your PC and all the peripherals from their outlets. After that, unplug all peripherals from the back of the computer. Move to a well-lit, static-free area, such as a tile floor or a kitchen table. Remove the computer case or panels to expose the interior of your PC. The power supply is enclosed in a metal box located in the corner of your computer case.

Before you disconnect any wires, be sure to sketch and/or note where and how each of the wires is connected. These notes will help you remember where to plug things in when you install your new power supply. In addition, when you remove any components from your PC, you should put any loose screws or loose parts in separate, labeled containers to keep them safe and organized.

Find the bundle of wires that come out of your power supply. These wires connect to your motherboard and various drives. Follow the wires to their white, plastic connectors and pull each connector until it is free (never pull directly on the wires). Remove all wires from their internal components. You may have to disconnect the on/off switch if the switch is not built onto the power supply. Occasionally, a large bracket secures a computer's power supply. To remove the bracket, loosen the screws and take it out. Now, remove the four screws closest to the outside edge of the computer case. Don't remove the screws that hold in the power supply fan. Carefully lift out your power supply (don't be afraid to pull it out with a little force).

To install your new power supply, you can reverse the actions you took to remove your old one. Put the new power supply in the same place as the old unit, tighten the perimeter screws into place, replace the bracket, and reconnect the on/off switch. Reconnect the wires by following your sketches and/or notes in reverse. If you have any loose wires, bind them together with a twist-tie. Make sure the voltage switch visible on the power supply is set at 120V (120 volts, common in the United States). Replace your computer case/panels. Connect all peripherals and the power cord to the back of your PC. Plug your PC and the peripherals into their respective outlets.

Start It Up. Turn on your computer and monitor. You should hear the normal sounds of a computer powering up, such as the fan and hard drive spinning. If your PC doesn't turn on or if any components in your system don't function, you should turn off your PC and unplug it. Remove the case and check to make sure all the wires are properly connected. Replace the case, plug in your computer, and turn it back on. If you continue to experience problems, contact the power supply's manufacturer or your PC's manufacturer.

'97 Honda Civic dome lights and keyless entry problem


The signal from all the door switches is fed to the factory radio. From the radio, the signal goes to the dome light. When the radio is removed, the dome light does not work since the circuit is "cut".
Fortunately, there is a very simple workaround this problem. If the car does NOT have a factory alarm/ keyless entry, all you have to do is tie two wires together.
There are two green plugs. Get to the one that is plugged into the radio (if you have both green plugs going into the radio, then you DO have a keyless entry system).
Tie together the Green/Black (at the corner of the plug) and the Green/Red (3rd pin, opposite corner, same row).
Before tying the wires together, test both wires. With the radio plugged in, both wires should get a ground when a door is open and nothing when the doors are all closed. Once you have determined that they are in fact, the correct wires, unplug the green plug from the radio. If the dome light still works, you do not have to worry about it. If it doesn't, temporarily jump with a wire both pins at the plug. If the dome light functions correctly, then you can permanently jump the wires together. The preferred way to do this is to strip some insulation on the wires, solder a jumper wire and insulate with electrical tape.
