Also , I am planning on getting the batt tested(old optima batt)
And I am planning on swapping the wire out , if both those show/do nothing I will be looking for another truck alt .. Prolly a new one, so my question is can I buy this truck alt at autozone? If so what can I type in to look it up? Thanks for the advice

Install the new wire otherwise we are all just guessing. If that doesn't fix it send me back that alternator and I will have it warrantied for you.
If you go to an auto parts store get an alternator for a 2003 chevy truck 5.3 engine 145 amp alternator.
Yep!
Well stocker finally quit on me. Going to upgrade to the kg3 145. My questions to you guys are. Is the replacement of the pigtail (4pin) necessary or only on the cars where the harness is to short? The big 3 wire upgrade where can I get it? or is it better to just do it myself ( getting the wire and the end links. If so how much wire do I need and do I run them inline with the existing wires or just in place of? Thanks guys I know these question have been asked a million times, just love my car and want to get it done right the first time.
P.S. Thanks again.
P.S. Thanks again.
went to the salvage yard today bought a alternator ($65 1 year warranty) off a 2003 silverado 145amp kg3 installed it ,bought the pigtail from oreilly pt1136 installed it, and NO MORE lights flickering and no more voltage drops. took it for a drive had the AC blasting the bright lights on and the 1000 watt amp system bumping full blast ,nice and steady at 13v. even turned on the blinker to see if the volt needle would pulse and it didint . just want to thank the O.P 00pooterSS for helping me through this thread and P.M's
Thanks :p
Like SJ said, newer ones have 2 pin connectors and will NOT work. If you can find a 4 pin it will.
Cool. Let us know how it goes.

ok, I just installed my 03 Truck alternator and the dash indicator is reading below 13. i took it to Autzone to test; shows my Alt. failed!... ARG!!! ok so now what? and a quick question... I want to make sure I didn't mess up the excitor wire (would that cause a fail?). How many wires are connected to the excitor wire plug???

If you didn't put a new exciter wire on it you're pissing in the wind, they aren't long enough and they do go bad.
Sounds like you had a bad one though if they tested it for you and they said it wasn't working.
On a side note, I sold my Camaro and bought a GMC truck and I am going to do this alt mod to it too since it only came with a 105 amp.

This mod was the best ever!! Made driving my car so much better. Fixed everything that was wrong with my car electrically(flickering lights,blowing fuses,idle,no dimming from the subwoofer, and just feels smoother all around). I couldn't be happier. If you are debating on doing this and have flickering lights etc. don't waste your time. Just do it
