What is the deal with the voltage dip when returning to idle

Anytime my car returns to idle, the lights flicker. I've heard of other people having this problem. But asides from the flash being the "cure", what exactly is causing it? I checked batt. voltage and it was sitting at 13.7 but hit the throttle and let it go and it goes down to 13.45 not that its a noticable difference but apparently something is "cracked out" in the charging system. Thanks for any help fellas

This has to deal strictly with the alternator, although a grounding kit will clean things up a little bit. We pretty much all have the problem, so that is good....(I guess). I've spoken with guys that have replaced the alt. w/ an aftermarket piece...and that has supposedly fixed the problem.

I've had my car in three or four times for this - the last time, my Ford dealer found a "charging system code". They replaced the alternator and it had absolutely no effect. I still get the battery light flickering occasionally when the car drops back to idle and sometimes when I'm sitting there just idling at a stoplight. The problem isn't really too annoying, but the fact that Ford seems to not have a fix for such a prevalent problem is... I guarantee that this will someday be a safety issue and then they will wish that they had moved their asses on this. By the way, I have also heard that the grounding kit helps, but I haven't tried it yet.
