So I finally got around to adding a temporary voltage meter for my audio system and I am slightly concerned with the voltage I am seeing. If I turn my AC and lights off after a few minutes of the engine running my alternator will completely stop charging and my batteries (yes there is a second one) will drop down to the mid 12V range. I turn my lights on and almost instantly jump back up to 14.2 and stay there. Is this some new age crap? My other cars have been 2005 and older and the alternator would put out 14+ regardless of the draw on it. Will someone with a multimeter go out and check their car after it has been on for a few minutes? Just turn all the accessories off that you can and see where your voltage sits and then turn your lights/ac on and see where it sits then. I would greatly appreciate it!
