I have a 2010 Grand Sport and it is supercharged by Lingenfelter. The "Service Charging System" light came on and I changed the battery along with two aftermarket alternators and system still not at 14.5. I went back and got a AC Delco OME alternator and still not charging at 14.5. Help

I would diagnose your issue before you throw anymore parts at it, the gauge in your car could not be reading correctly. Here is a good video to start with.

Any other suggestions? I still have the same issues and the battery checks good
