(2015 Silverado LTZ 6.2) So over the last few days I've been recognizing the Battery saver active notification on my truck. I recently installed a Mechman 250 alternator and a new battery, got a stereo system put in and it didn't have enough power for it so I did the big three Upgrade. I'm getting great voltage but after a while of driving I get the (battery saver active) warning does anyone know what that could be I'm kinda lost.
