Hey guys, i'm driving today in my Acura TL 2010 shawd and the check charging system light came on. I did a quick google and it told me that i should turn all electronics off. I immediately turned off my AC and my radio and 2 min later the light went off. I went to autozone to have my battery and alternator checked and the guy said everything was 100%. I went home to check it myself to make sure. The battery without the engine on was 12.8 and then when i turned it on it says 13.75. This tells me batter is fully charged and alternator is good right? So what should be the problem? This battery was replaced in august. So its a new battery. I'm not sure if this matters but i have about 70k mileage.

Thanks in advance

 

Does anyone have any ideas?

 

I thought there was some software that managed the power too. I believe someone said a dealer updated it or did something to it. (This is from my rumor and myth catagory cause I am not sure)
