i would just give the regulator a try. both of the replacement alts that i put on were brand new delco also. i got the reg off ebay. it's just a cheep one but it works great! for $8.00 you can't go wrong trying it. if you decide to do this make sure you have a solder gun.

I'm running TWO motorcity reman'd alternators, one in my red TA and one in my black TA... Both 160 amp.
The red TA charges FINE, the black TA drains/dims at a stop in gear when the fans are on, badly, to around 7/8 volts... Then I blip the throttle and they go up to 12/13.
Soooo...
I've switched alternators between the two... No change.
Then, I switched batteries between the two while the alternators were still switched... NO CHANGE! lol
These problems don't necessarily have anything to do with alternators, guys... I checked all grounds, and all battery cables/terminals, grounds are clean!
Still trying to figure this out myself.
Just raised the drive idle and neutral idle of my black Trans Am to 600 and 850 (I throw it in neutral at long stops and red lights), and it's driving me less crazy now... But once the fans go high speed, it doesn't matter what alternator is in the car!
Anybody?

Really? I noticed that the flickering doesn't happen when the key is in the on position but the second I actually start the car it flickers then goes away once warmed up. I will double check the ground on the head, but if it still does it what could it be? This is pissing me off lol

I don't know how so many people have charging issues, especially with these aftermarket super-duper alternators.
I put a PepBoys Pro-Start in mine I think like 5 years ago, lifetime warranty and its 100% perfect.
It doesn't falter AT ALL....even with a 1000 watt stereo blasting with a 12" woofer hitting, lights on, A/C on with fans on high with my 427ci.
Whats the deal?

It's not a charging issue at all. My battery and alternator are 100% fine.

it might not be. i put 2 brand new delco alts in mine and had the same results, flickering lights and voltage jumping around. so after checking all grounds (not kidding) front to back on the car and testing the signal wire from the pcm to the alt, i came up with nothing. on a hunch i bought a voltage regulator off ebay for 7 or 8 bucks. i figured i can't go wrong just trying it for the price. after i installed it in my original factory alt i started it up and all was normal again. if you have checked everything els and still couldn't find your problem, i would just give it a shot might work for you might not, but it worked for me. for the money i think it's worth the gamble.

i hope your not going to buy a delco. thats what i did twice and both performed the same as my bad factory one. put a new regulator in and i was good to go and still going strong today. i wasted so much time trying to find the electrical problem and there wasn't one. spend the extra and get an oem alt, or try replacing the regulator on your factory alt.
