    Hi guys,
    I have a 05 2500HD Silverado p/u and the alt. gauge is over passed 19. I checked the voltage and it is at 13.5. Is the cluster bad or is it something else? And if it is, is there a place where you can get them rebuilt or do you have to get one from gm? Sometimes It will work when you start it and then go over pass 19. Need help.

    Thanks Dale
