I am having the same issues as some of the other people with this truck. This morning I started my truck and it started up fine. Then as I am driving down the road about a half a mile I got a message from the truck saying that the charging system failed and the battery light came on. I have had the alternator tested and need to get a new one but when I look for the code for the alternator and call a mechanic he is telling me that my truck should not have a KG3 it should have a KG8 or something else. As far as I know this truck has not had any wrecks and so I do not know why the glove box would have been changed. Can you help a girl out?
Thanks

Hi and thanks for using 2carpros. Com

KG8 indicates a 130 amp alternator. There is no KG3. Where did you get that number?

Now, there is a technical service bulletin (TSB) related to incorrect coding. The alternator in your truck should be a 145 amp alternator. Take a look at this TSB:

ALTERNATOR - INCORRECT AMPERAGE CODING
Bulletin No: 04-06-03-001

Date: February 03, 2004

INFORMATION

Subject:
Incorrect Amp Code On Generator

Models:
2003-2004 Cadillac Escalade, Escalade ESV, Escalade EXT
2003-2004 Chevrolet Avalanche, Express, Silverado, Suburban, Tahoe
2003-2004 GMC Denali XL, Savana, Sierra, Yukon, Yukon XL
2003-2004 HUMMER H2

The purpose of this bulletin is to inform the technician of an incorrect Amp code stamped on the generator. The code on the side of the generator reads 130 A and it should read 145 A. The 130 A has been stamped on the generators in error and does not indicate the actual amperage of the generator. A 130 A generator is not produced for this vehicle. The correct replacement for the above vehicles is the generator with the 145 A marking.

With that in mind, I believe the alternator needed is GM part number 10464476. However, that must be verified by your mechanic.

Let me know if you have other questions.

Take care,
Joe

I got the code from the glove box in my truck. I called the auto parts store and gave them all the information for my truck and they still gave me the incorrect alternator. I did get the correct one last night and it didnt take about 10 mins to change them in the truck and things worked out after that. I guess the best thing to do is take the part ( alternator in this case) to the auto parts store and compare them before you leave the store.
