Alright so apparently my car is out to get me, my car is now having a issue with the battery. when turning on my car the car turns on but everything electrical runs really weak, A/C, windows, Dashlights, and the battery light turns on on my dash as well and the battery gauge reads lower than where it should be. well it will do this for about 10 minutes then everything it go to normal the gauge will just flick over to where its suppose to read and the battery light will go away and the lights and A/c and everything will go back to normal. well it did this for about 2 days everytime i parked my car for a couple of hours. well i took it to get checked and they told me my battery and alternator are fine and didnt know what else to tell. They are both about a year old. just wondering if i could get any advice from you guys. i check my battery terminals and while a little dirty nothing that i would imagine would cause this problem but i cleaned them anyways. then i checked my alternator wires because i thought maybe i pulled one while doing a oil change but they seemed fine as well. any suggestions? you guys were helpful last time so figured i'd check here again
