Here's my dilemma. I recently, like a month and a half to two months ago, put in a new battery and alternator from Advanced Auto. Now I have been noticing that when the headlights and A/C and all other electronics, including stereo system, are on at idle the volts are dropping to below 12, somewhere in the 11-10.8 I believe. Once the A/C is off there is no problem, the volts jump right up to about 12-12.6 or so. Now I have tried disconnecting my radio and amp so there could be absolutly no draw and still have the same problem. Does this sound normal, I heard that as long as the volts are above 12, even 12.2, then your system is charging fine. Please help, thank you.

P.S. Yes I have tried searching the forums and have come up with nothing.

Advance should have a alternator tester, and should test it for free. Go by there and have it tested. Chances are you got a bad alternator.
