I had a friend contact me with the local Police Department and they have five 2011 Camaro SS Automatics they are having issues with retaining a charge on the battery at idle. Their equipment causes a draw on the battery to the point that if the car idles long enough, their electronic equipment will begin to shut down and in several cases, has killed the battery. I saw a whole segment related to the alternator's performance for the 2010 and up Camaro in the System section. Can someone who has experience with this issue assist in what changes would need to be made to the alternator segment to increase the output at idle or lower speeds?
Thank you -
