After the battery died, the car radio stopped working? What do you know about fixing a car radio that stopped working after the battery died? If you’ve heard this one before, pause. Your battery died because you left your headlights on. Or it simply died because it was old, it was chilly outside, and nothing lasts forever. In any case, the battery died, and you had to deal with it: a jump start, a battery charger, or even a new battery, and you were back on the road. Isn’t everything fine? Except now your radio is broken. Repairing car audio that stopped operating after the battery died is usually easy but sometimes it can, of course, be far more complicated.
Deciphering The Bad Battery And Emptier Car Radio Code
After the battery has gone fully dead, a car radio can stop working for a variety of reasons. The first is that the radio includes an anti-theft “feature” that activates whenever the battery is removed. When this happens, all you have to do is input the correct auto radio code to get back on track.
- Protection characteristics
- If the word “code” lights on your radio, this is most likely the problem.
- When the battery dies or is without connection, car stereos with a code feature ask you to enter a preset code.
- You may find the code in your instruction booklet, or you may need to call a dealer.
- A jump start resulted in damage. If safeguards are not taken, electrical system components can be destroyed during a jump start.
- Before you condemn the radio, check the required fuses and fusible linkages.
- If the radio has both power and ground, it is most likely defective internally.
- A complete coincidence
- A broken car radio could be the consequence of a dead battery or a jump start, but it could also be a curious coincidence.
Car Radio That Stopped Working After Battery Died Problems With Code
Your radio doesn’t have a security code? All the fusible connections and fuses are fine? You’ll need to conduct some extra diagnostic work. This is vital to figure out what’s wrong. The purpose of car radio codes is to operate as a passive anti-theft device. When the radio’s power is cut, the function activates. When power is on again, the unit is effective with a brick until a certain code is on its end. Depending on the manufacturer, the readout may display the ever-helpful word “code,”. In some cases, it may remain blank, or it may display an even more obtuse message.
This feature is generally found on OEM head units, and thieves primarily target aftermarket head units when stealing car radios. As a result, car radio codes nearly always become hassles for the rightful owners of those car radios. It’s rather than the thieves they are supposed to annoy. The best method to handle a car radio code is to ignore it completely. If your radio has this feature and your battery hasn’t died yet, you should figure out the code. Then write it down as well as the reset method ahead of time.
The Risks Of Charging Or Jump Starting A Car Incorrectly
If your car radio still won’t turn on after a jump start or a battery charge, the issue could be due to a car radio code anti-theft feature. You should eliminate that possibility before proceeding. Check to see if your radio has that functionality, and if it does, make sure that inputting the proper code doesn’t bring it back to life. If it doesn’t, you may be dealing with a more serious issue.
The problem is that while jump starting or charging a car battery is entirely safe when done right, it is incredibly dangerous when done incorrectly. The most dangerous aspect of jump-starting or charging a battery is the explosive nature of hydrogen gas leaking from a lead-acid battery. This is why the final cable you connect should always be a ground cable that connects to the ground instead of the battery. If you connect directly to a battery and the battery has released hydrogen gas, the spark could ignite the gas and create an explosion.
Aside from the dangers of a car battery exploding, which I’m assuming didn’t happen because a dead radio would be the last thing on your mind at that moment, incorrectly connecting jumper cables or a charger can also cause electrical system damage. If the connections were ever connected backward and your radio ceased operating as a result, the radio could have been fried. Aside from your radio, a variety of other components could be fried as well.
Fuses And Fusible Links When Come To The Rescue
Unlike people, who may spend their entire lives looking for meaning, fuses are born into this world knowing that they will one day die to rescue someone else. The vehicle radio fuse, for example, is with special construction to sacrifice itself. It prevents a dangerous level of electricity from running through your car radio and associated circuit.
If you’re lucky, your car radio fuse will be blown if your radio is dead as a result of a botched jump start or charge. It could be the fuse inside the radio. In some circumstances or the fuse in the vehicle’s fuse box in others. In other circumstances, you might discover that a fusible connection has blown or that a wire has melted someplace. Other electronic components, including your incredibly expensive electronic control unit, may have been with damage in far more dangerous conditions.
This is why it’s critical to know how to jump-start a car using a jump box and to never, ever let anyone, no matter how well-intentioned, hook them up incorrectly. After all, just because someone is a kind Samaritan doesn’t mean they know anything about automobiles. When two things take place simultaneously, it’s natural to assume they’re not some connection. And there’s a good likelihood that the problems with dead batteries and dead vehicle radios are with the link. However, it’s possible that your automobile radio stopped working for no apparent reason.
Fixing A Car Radio That Stopped Working After The Battery Died Final Words
If your radio goes on and displays a station but no sound emerges from the speakers, the problem is most likely with the speakers, wiring, or even the antenna. In a similar vein, if other audio sources, such as the CD player, are working properly. Car stereo with a non-functioning radio maybe with a tracker to bad radio reception caused by difficulties such as an antenna problem.
