I noticed that my battery light flickers ever so slightly under hard acceleration.
It starts flickering at least 5500 rpms and so on. But I can still daily without having my battery drain (no battery drain at all)

New Reman Alternator from autozone
Checked ground from alternator and is good.
Belt is tight
Harness Plug is plugged in
Battery terminal is tight

Engine: B20V B16 Head
Reman: Alternator from OBD1 b16 Delso 80amp

 

Maybe I need a OBD1 GS-R Alternator (90AMP)??

 

probably all boils down to it being a reman alternator...

 

Well I took it back to do a restest and it past. took it to local shop and said it pass...so i'm lost on this...

 

"Flickering" Alt./Batt. light at high RPM is an indication that the alt. brushes are worn out or sticking. 94

 

The voltage regulator is responsible for grounding that circuit to make the batt light come on. It's likely that the reman alternator may still function to charge the battery but have an issue within the internal regulator.

 

Voltage regulator is going bad. Most shops can't check for high voltage issues only low.

 

Take the car to an alt./batt. shop, [Interstate batteries] and have them do a proper load/charging system test, it is free a most places and only takes a few min. 94

 

This.

And just because it passed a vatozone with the 2k rpm test means nothing. It might be charging at proper voltage at low rpms but overcharging (too many volts) at high rpms.

 

Thanks for all the help. It ends up being the alternator it self. I guess it was defective...So I had them to order me another since they were out of stock in my town. Replace and now revs without any flickering light. :D

 

It takes, on average, two autozone returns to get a good alternator.
