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.

Thanks for the donation

Please let us know if what the final fix was for your car so we can better assist others. Thanks!

Hello –

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?

I do know this much so far: No error codes stored in computer. Alternator diode pattern is bad (same as on the last two) and battery check tests bad. I am installing a new battery and another rebuilt alternator. Same question: what is causing this?

It lools as though it was the 95 amp model, because that's what the original was. The model year is 02 but the vehicle was purchased in late 01.

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 –

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.
