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.
To start, assess your wiring. When you own a voltoltage meter or even a test light, examine the bottom (black), constant 12v (yellow), and accessory 12v (red) wires to create see in case you really have the right voltage within the right wires, and also 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 rear of the radio. Guarantee the harness is connected to the port on the radio, which it's fully seated. Be certain the power antenna lead is not linked to the remote turnon lead, when an external amplifier is used. These wires regularly look very similar, and may be complicated if the labeling on the wire 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 find that one of the power wires or ground wires aren't correct, review your automobile wire diagram and ensure you've got the proper corresponding power and ground wires.
If you do not hold power, and you know for a fact your wiring is right, check the fuses under the dash or under the hood (depending on your vehicle). Simplest solution to locate the right fuse will be to check within the Owner's Handbook and find the fuse number as well as box location. Your manual should indicate which fuse is for the "Accessory", "Car Stereo", or something of the sort. After locating the location of the fuse, pull it and make certain the prospects aren't corroded and the fuse has not been broken or popped.
