Do I need a fuse for my radio?
A Fuse Needs to be Replaced. A car radio will have at least one fuse to protect the unit from things like power surges or other electrical issues. If too much current is sent to the audio system, this fuse will blow out and disconnect the circuit to save the main radio.
Why does my no power for radio no blown fuses?
If it worked before you started then something got pulled or a fuse is bad, especially since everything else works. If there are any solder-less connectors in any of the lines check those as well. Sometimes those connections come loose or were not crimped properly. I have had that happen on several occasions and I am usually pretty darn careful.
How can I tell if my fuses are still working?
The #12 fuse location is central to the circuit, so finding out if power is present there will tell us which way to go. Here are the other circuits the fuse feeds… just in case one or two may still operate. Check a few of these other systems to see if they operate or if it’s isolated to the radio and dome lamps.
How do you replace a fuse on a car stereo?
There are usually spare fuses in the box, so you can replace the fuse with the same rated fuse. The size and color should match the existing fuse. Step 3 Remove the car stereo from its internationally standardized slot in the car’s dashboard known as a DIN — Deutsches Institut für Normung — slot.
How to troubleshoot a car stereo that will not power?
Take a close look and make sure no wires are loose entering the harness. Make sure the harnesses are plugged into the car stereo. Trace back wiring from the car stereo’s control head power harness to the fuse block and verify that the wiring is all intact. If you encounter a fuse along the red wire, replace it.

What causes a fuse to blow on a stereo?
Vibration can cause wiring to become loose. Tight working-space confines can create difficulty making connections in the first place. Turn the ignition key to the accessory setting and press the “Power” button a few times to verify the condition. Check that the stereo circuit fuse hasn’t blown.
Why is my JB fuse not working properly?
It also shows a splice internal to the JB that splits power to the various places it serves, so with the entire M1 circuit deader-n-a-doornail, the problem appears to be within the JB itself. Pull that #12 fuse out to check the terminals for burning or damage.
