Hi guys my car stereo suddenly stopped working. I replaced the license plate bulbs i forgot to turn the ignition off anyway i burnt 5a fuse which was in the trunk Fuse box . The surprise is the stereo stopped working there's no power to it at all we checked all Fuses under rear seats fuse boxes and in the trunk box all fuse working fine . We pulled the stereo itself and my mechanic friend said there's no electricity in the harness the stereo the unit itself is fine . Is there any other Fuses boxes? We checked every fuse box under the hood , in trunk and both heelboard box .

Any other Fuses or relays??

Thanks

 

Update the cigarette lighters doesn't work too .

 

Why type unit do you have, standard or premium?

 

Thanks for the diagram . Its standard unit . Checked all Fuses all working fine both cigarette lighter doesn't work too any ideas?

 

Which 5a trunk fuse did you initially blow? What does it go to is what I mean.

 

I honestly don't know what does go it some xj fuse diagram shows different things and im not very good at car electronics . I checked the Fuses after the license plate lights stopped working then i found blown 5a fuse the lights turned on but stereo and lighter are gone . Could it be anti theft system?

 

Without looking at a fuse diagram, I highly doubt it has anything to do with anti theft. My daughters 98’ XJR has the fuse diagram on the trunk fuse box lid. I’ll snap a picture of it in the morning and post it here.

 

So, you need to go to the Audio System fuse and have your mechanic check whether you have power at the circuit there.
It would benefit you to pick up an owners manual. It will detail all this for you. As a matter of fact, note in the top left (4-20) is the page from the owners manual.
You don't need to know electronics to figure this out or to tell Addicted which fuse it was.

 

I pulled fuse number 3-4-5-12 all are fine . My friend also checked every fuse in the car both heelboard and under the hood also . Nothing working there's no power in the stereo harness

 

So, has he checked the Audio Sytem circuit for power? ...where the fuse is (#3), not the stereo.

 

Yup checked the audio circuit and there's no power.

 

With the key on? I believe that circuit goes off with the ignition. If so, then you may have an issue in the ignition or on the back side of that fuse box. Be sure to check your grounds also.

 

You mentioned you pulled the radio which means the center console came out if memory serves me well. There’s a harness that may have been left unplugged for your cigar lighter.

 

It wasn't the Fuse it was the relay in the trunk i tried to upload picture to show which one but couldn't upload it

 

Was it the black relay ?

 

or if you can mention its part number. Will highly appreciate
