Truck Broke, need help....

[Rollin Thunder]

not sure may even be the orig?? Its AC delco. is there a decal to see when it was produced?

It acts like its going through a relearning process. Take your battery and have it tested to see if its still good or not.

My truck did the same thing a year ago so i changed the alternator and all was fine after that. keep us informed. GL

A battery can only do so much, the stock alternator is only 105 amp, you should look into at least a 145.

I thought the stock alternator is 160 amp

For an 03 Silverado?

On Edit: the 05 Tahoes have the 145 since they have the e-fans from factory. That is probably what you are thinking.
