Order a KG3 alt from a late model truck, all the information to get the right alternator is in the first post of this thread.

i didn't even know i was having an alt problem until i read this post. my headlights were dimming and my voltage was dropping below 13volts. i just thought it had something to do with some other problem i was having. after i had fixed the other problem i noticed i was still having this problem. i just so happen to stumble on this thread and i realized that my alt is going bad. now here is my question. i have the racetronix voltage booster which is connected directly to the alt, along with the the upgraded fuel pump in tank. i was wondering will there be any problems if i put the 145 amp alt on my car? it wont overpower the fuel pump? or prematurely wear it out?

If anything you will now get the voltage you were supposed to be getting to the pump since the alternator will charge properly, if you have low voltage now then the pump has been underpowered.
It will be perfectly fine.
One last thing, the pump PULLS the amperage it needs, this is different than voltage. The amperage is there for the usage but the pump will dictate how many amps it pulls from what is available. Now on the voltage, if you supply it with more voltage it does work the pump harder, so if you now have low voltage you are underworking it. The voltage would be more of a concern, but again the voltage is regulated on the alternator and the pump is built to operate in the regulated range.

I rarely drive my car at night.
during the day the charging sys. is below 13V I estimate 12V going by the OEM guage (thats w/ radio, AC Bi level vent not AC turned on).
last night I was cruising down the expressway as usale 12V then I turn on my headlight atl. was then charging at well above 13V I estimate 14V then I turn on the AC and it stayed at 14V even parked at idel I had 14V (it stayed at 14V w/ high beams on also.
so why doe's the atl, charge normal w/ headlights turned on doe's this sound normal?
Thanks

Your problems above sound like alternator or maybe even ground issue's. Check all your ground wires, take the battery connections off the battery and clean them really well, CALL LKQ like I said and order the right alternator, get a connector for the alternator from NAPA or Oreilly and install that. Everything you need to do this right is posted in this thread. If you still have problems after you do all the above things take it to a shop. There is only so much that can be diagnosed over the internet and your problems are beyond that. And stop asking for a AD244, nobody at a parts house or junkyard knows what that is. It has been posted so many times to get a KG3 option alternator.
Here is the information for the connector
AC Delco part PN# PT1136
I got mine from NAPA so you can try going back there or go to orielly

Well, my friend and I ended up changing the alternator and going with one that came from a 2002 suburban. Like pooter said, it worked and fit well. For our sanity, we also changed the positive battery lines and the starter, along with adding an extra ground. So far, it lasted the ride to get the kids from school. When the rain passes, i'll bust on it hard, back to back. If it holds over that, we'll have a winner. Thanks again for posting!!

No it doesn't sound normal and until you put a known good alternator and new control wire/pigtail on it like I been suggesting I cannot help you.
Your problems above sound like alternator or maybe even ground issue's. Check all your ground wires, take the battery connections off the battery and clean them really well, CALL LKQ like I said and order the right alternator, get a connector for the alternator from NAPA or Oreilly and install that.

did the new connector from NAPA have the same color wires? and a decent weather profh cover?
looks like the alt. needs to be removed in order to unplug this connector is this true?
I crawled under the car and connected the 3rd big 3 wire to alt. and ran it up to the + of battery will connect to + battery this week.
Thanks

the alt connector is the same as the windshield washer connector. but it comes with all 4 lines instead of 1. you can unplug the connector from the top. its right there.

when you changed the connector did you lenthen the wires and soider the wires?
