How To Fix Car CD Player Not Working After Changing Battery

If you have changed the car battery fitted to your vehicle recently and your CD player is no longer working, most people would take it to a electronics specialist like AutoZone. If your radio wont work after a dead battery that just died, sometimes when fitting a new one the voltage can spike. This can blow the fuse on the car headunit or the circuit that provides 12 volts to it directly. So checking the fuse locations is certainly something you can look at to see if you can fix this problem but there is no guarantee a first time fix.

Checking For Blown Fuses on Car CD Player

1) Firstly you want to see if the fuse for delivering power to the stereo functions or not. So you will need to refer to the car user manual and find the pages that show the fuse locations. You will need to find the fuse that is labelled as 'Radio/Stereo' fuse.

2) Find the fuse box location. In most vehicles its fitted inside the engine bay or underneath the car steering wheel.

3) Pull out the radio fuse. Look directly into the middle area. If the wire looks burnt or snapped it will need replacing. Remember to replace it with one that is the same amps. Using incorrect fuse ratings will defeat the purpose of protecting the circuit as it will not be affected if a short does happen damaging your equipment permanently.

If the doesn't resolve the CD player not working after changing the battery problem, you will now need to check the internal fuse either on the stereo itself or the attached wiring harness on the yellow or red power wire. You will require din tools to remove it from the slot of the cars dashboard plastic trim.
