Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Have the alternator tested for correct charging.

Yes, it does look like the wheel well will be the best access point for your alternator..

Hello -

To better assist you is your vehicle just a GLS or LX. Also please tell me the engine size in liter and the 8th digit of the VIN.

I know you check the voltage across, but please go to Auto Zone (AZ) or and have them pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. This is the main thing here, have them bring their tester out and check your battery and alternator with their tester.

Well, I wouldn't say you are the unluckiest person. . .. . ...at least they are free each time. . ..

Now, I do see a TSB that increased the V6 models from 95 amp to 110. . ...which one are you installing since AZ has both?

Hello -

My previous question to you was what amp alternator have you been installing?

Hyundia does not provide instruction see diagram is that like your set up?

Hello -

Thanks for the info.

Obviously I don't know for sure about why you keep burning them up... But...I am going with the TSB that the V6 models need the 110amp.

My thought...(See what you think)..... The 90amp is running all the time with no rest and burns out the diodes because it is too weak.........

At a certain point since it isn't putting out correctly it is going to affect the battery.........

Hello -

Thank you for the update............. Good luck

Hello -

I was reviewing previous posts and wanted to provide you with this info. Looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
