Depending on the make model and year, you may have two power sources. One for radio memory, and one for radio operation.
The memory could be tied into the cig lighter or other circuit.
my guess is someone has installed an aftermarket radio?
your yellow and red wires are backwards on the back of the stereo. you've got constant 12v power going to the ignition/memory wire on the stereo.
The wire that connects to the panel for the radio fuse might be loose or broken. Pull the fuse panel out and check the wires, disconnect the battery first, or your gonna have even worse problems
Terminals for what, the battery? Anyway, you likely blew a fuse-check the fuse panel under the dash-should be a radio fuse. Radios often have two power sources, both would be fused, sometimes a power wire has an inline fuse. If you find the radio fuse and it is good, better use a test light and check that your fuse panel is getting power to it. The radio fuse would have power to it with the key in ON. In fact, with key on, every fuse in the fuse panels would show power on a test light. The little slots at the top ends of every fuse are open to the metal strip inside the fuse. Ground the test light lead to a metal bracket or screw, and touch the test light probe into the slot. With key on, every good fuse will light the test light on both ends of the fuse-fuse is good and has not blown-a bad fuse will only light up the test light on one end of the fuse-the metal strip inside has blown apart. You can check all your fuses this way-don't have to pull them out to inspect. But also most important for you to know is, does your fuse panel have power being fed to it. If those terminals were battery terminals, you may have blown a bigger fuse that feeds the fuse panel, one of your maxi fuses under the hood in the Power Distribution Box. Good luck. Post back with what you find.
Easy way. With a test light connected to ground ( a test light is a tool that looks like a ice pick with a clear handle with a bulb inside, and a wire coming out the end with a clip on it) Connect the clip on the light to a metal ground under the dash and with the fuse panel where you can see it, touch the pointer to each side of the back of the fuses, with the key on. The light should lght on both sides of a good fuse. If a fuse lights the light on one side and not the other it's blown. For the radio to work three fuses all need to be good as theirs all the time power and key on power and lighting as the dash lights power. The cigar fuse many times provides the all the time power, But if it's blown the radio won't play. Pull one fuse at a time and look at them to see if the bar inside the fuse is good ( they can look good and be bad) back to the test light meathod, Look the fuses up in the owers manul and it'll tell you the location of the fuse but the radio fuse can be good and the radio strill not work as the cigar fuse has to be good too, There;s another fuse panel under the hood that has the main fuses near the battery, Again the test light is fastest and easiest as any fuse blown even though it's not the radio fuse can make the radio not play. Aftermarket radios can have inline fuses instlled by the radio installer and some have fuses right on the back of the radio.
The fuse you are looking for is located in the passenger compartment fuse panel. It will be in the number 8 position (see layout diagram below). That fuse covers both of the things you were looking for but also in the number 11 position is a separate fuse for just the radio. This should be in your owners manual if you have one. If you don't and would like a copy, you can email me at [email protected] with your make model and year and I will be happy to email you a copy. Don't worry, no cost to you. I hope this helps and good luck.
Ouch! Okay, do you have a volt meter? If so you need to check the voltage at your fuse box to make sure that you are getting power to fuse panel If you are getting power to the panel, then you have to diagnose the power issue from the fuse panel to the radio and dome lights. All the lights not working? The radio may have an in-line fuse as well. If you don't have a volt meter, go get one.
Double check the fuses. Also, there are usually TWO fuses for the radio. One has power when the car switch is OFF. This keeps the clock working and your radio presets set. The other is when you turn the key on. The horn not working can be tested if you have a 12V test light (Wal*Mart sells them...). Unplug the horn, hook up the test light, press the horn button. If the light glows, you've got a bad horn (go to your local junkyard for one). If not, recheck ALL the fuses. Good Luck
Make sure and check both fuses.There are usually 2 for the radio.One for clock and lighting and one for power.There is a fuse panel on the passengers side also.So there is one fuse panel on the left side of the instrument panel and one on the right.One fuse is in the left and the power fuse is on the right side panel.Hope this helps.Good luck.
Check your connections again. Check that they're connected correctly. Look at a diagram, check the fuse on the power (red) wire from the radio. The radio might have fuses on the back of it, check them too. If anything put and tape every thing back together and use a harness then go from there.
