I go and jump start my car. When i pull the jumpers off the other car. My Hyundai will stay running for about 2 minutes and then dies. It has a brand new 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

how can you have a brand new battery and no power...
fix this problem first

Yes... Your battery died. But why?

First, leave the cables on longer, a good 10 or 15 minutes. When you hear that clicking noise, it's because there is not enough power available to turn the starter. It means you need more power. Leave the jumper cables on for a few more minutes and you will have the power you need to start the car.

Once the car is started, remove the jumper cables and pull the positive (Red) cable off the terminal on your battery. If the car stays running, get a new battery. If the car dies immediately after pulling the positive battery cable off, then your altenator has gone out. The altenator is the electrical generator that provides electricity to your lights, engine, stereo, AC, etc. It should be putting out about 14.2 volts. Since your car is a 12 volt system, there are a couple of extra volts to spare, which are used to recharge the battery. It takes a lot of power from a battery to start the vehicle. That's why the alternator is there to takeover after startup, plus recharge your battery in the process.

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

you may have a bad ground, or the ignition switch needs to be replaced.

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.

your alternater could be bad and not charging the battery, get it cranked then remove a battery cable. If it stays running, alternater is good if it dies alternater is bad

Sounds like your alternator is bad, if car will stay running long enough to get over to an auto parts place where they can do an alternator test for free have it check or you can remove alternator and take it to them so they can test it. or with a volt meter start car remove jumper cables and check voltage at battery, should have no less then 13.5 volts, what your checking is alternator output voltage.

YOU DO.
Pull another car or battery to front of car ,,and get the set of jumper wires (RED/BLACK) Red lead goes to Poss term (the biggest one) on both cars ..
Then the black lead goes to the earth side of battery
When started let engine run for 2 minutes and then remove the Black lead first on both cars then the Red lead,then let it run for about another 6 minutes or take it for a drive ,,,but connect the leads around the correct way to batterys......

Check the NEGATIVE battery cable from the battery to the ground pont
