Car Stereo Installation Help No Power To New Head Unit
Car stereo systems can have their share of exceptional challenges, notably for the beginner. Unexpected issues can appear, including the radio powering up but outputting no sound. There are some typical causes that can easily be checked sequentially with troubleshooting steps.
First off, assess your wiring. When you have a voltoltage meter or a test light, analyze the bottom (black), constant 12v (yellow), and accessory 12v (red) wires to create see if you have the proper voltage within the proper wires, along with a great ground.
Constant will be 12v, whether or not your car is on. Accessory will be 12v only when you turn the key to the "ON" placement or the vehicle is running.
In some instances, car stereos don't come wired with a 12v Accessory/Ignition wire, making an aftermarket radio difficult to put in and function correctly. Many Jeeps and Chevrolet systems have a data signal cable that carries a very low voltage signal that tells the OEM Head Unit when to turn on, nevertheless; it isn't compatible with aftermarket units. The easiest approach to locate an Accessory/Ignition cable is to locate a cigarette lighter that turns on when the automobile does. Get behind the ignitor and make use of the positive wire and link it to your RED Accessory/Ignition wire on your aftermarket wire harness.
Access the backside of the radio. Get the harness that has the green and gray speaker wires. Ensure that the harness is linked to the port on the radio, which it's fully seated. Make sure that the power antenna lead is not connected to the remote turnon lead, when an external amplifier is being used. These wires frequently appear very similar, and can be confusing if the labeling on the cable is disregarded. Sound will cut-out with the de activation of the tuner, once a CD is inserted, if this is the case.
If you discover that one of your power wires or ground wires aren't correct, check your vehicle wire diagram and ensure you have the proper corresponding power and ground wires.
Simplest solution to locate the right fuse would be to look inside the Owner's Manual and find the fuse number as well as box location. Your guide should indicate which fuse is for the "Accessory", "Car Stereo", or something of that kind. After choosing the location of the fuse, pull it and make certain that the prospects aren't corroded and that the fuse will not be broken or popped.
