No audio sound from my 2003 Sonata after jumping a battery.

Sounds like your alternator . Charge the battery , so it will start without a jump. you can check voltage while it's running . Voltage should be 13.5 volts or more

Its most likely a worn down battery. They get even weaker when its very cold outside. I'd get a jump or connect a charger to it.

Sounds like you might have a bad connection at one of the battery cables, a bad cable end, or maybe even a bad cable itself. Check that the connections to the battery are clean and tight.

Did you replace the bad battery cable with a new one ?

some alternators need battery voltage to stay running and after killing a battery if may not recover and you will need to replace it then i would check the fuses its posible that when first jumped the cable where on backwards

I'm not sure if the Aurora is a special type of car that requires a different way of jumping, but when u jump start most cars, you place the red end of the jumper cables on the positive/ red side of the battery and the black end on the negative. You want to make sure the jumper clamps are touching the metal part of the battery post (so if there's covers on the battery posts, move them so the cables have good connection. The same procedure is used on both cars. Be careful not to touch the end of the cables together, as doing so will make them spark if one end is connected to the running vehicle. Let your car charge a minute then try to start. If it starts, let it charge for 5-10 minutes and run/ drive your car after disconnecting to make sure the battery does not die the next time you shut it off. If it does not start after a few minutes of charging, adjust the clamps to make sure they have a good connection, wait 2-5 minutes longer & try to start your car again. *It is normal to hear the car that is jumping you idle more quietly when your car starts pulling juice from the charged battery. Also, remove jumper cables after charging, making sure not to touch the ends togther- as it will spark again. *it is not necessary to shut off the car that's jumping you before attatching the cables, or after charging. If your car still doesn't start after repeatedly adjusting cables and trying other cables to see if it is the cables not working, you may need a new battery or alternator. I would have the battery tested to see if you need a new battery before considerring the altinator.

Dear,

this car is equipped with the electronic fuel pump.............
please check the water level of your car battery and get it recharged from the workshop and also check the life cycles of the battery....if the battery is not ok...........then please get it replaced.


hope this solves the problem

thanx

Not the battery. Once the car is started, a bad battery will not cause it to stop running all of a sudden.
For engine to run you need - compression, air, fuel, spark.
Might want to check out your ignition coil for an intermittent condition - try replacing it.
And if it does not turn over(crank) check the wiring going to the starter motor,solenoid, for good connectivity. And make sure that your fuel pump is always getting power and pumping.

Wiring problem or the ECU (engine control unit) is defective. Try this, disconnect the battery cables from the battery and short/touch them together for 30 seconds (do not do this if connected to the battery). Then, reconnect the cables to the battery posts & see if that fixes it. If it doesn't, then there is a wiring problem associated with the cam pos snsr or the ECU has gone bad.

Thatttttt's alternatorrrrr.

Your alternator charges your battery. No alternator, no battery charge.
