It's likely that the reman alternator may still function to charge the battery but have an issue within the internal regulator. Honda-Tech Member

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.

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 B*a*n*n*e*d

Why does my battery light flicker when I accelerate?the alternator regulator warning light is connected to the shift light, so when the regulator isn't working, or isn't seeing enough voltage it flickers the shift light.
Why is my battery light on but alternator is good?The alternator belt is the connection that interfaces the crankshaft and alternator together. If your car's alternator belt isn't working properly, your car battery won't get the charge it needs for your vehicle's electrical parts. With that, your car battery light will frequently be on to indicate such an issue.
Can I drive with a flashing battery light?Driving with your Battery Light on is not a good idea. If the battery is bad, the alternator is faulty, or the wiring is bad, these can cause the vehicle to lose power and not operate like it normally would.
