I cannot believe the Corvette does not show that the alternator does not show that the car is not charging. I have a thirty year old corvette that will show you when the alternator does not show the car has an under performing alternator. If you do not have it showing on the display it will not show you that the alternator is defective. You have to show it on the display you never know you have a problem. It is an issue that is not a problem unless you know. I bought a battery and it was the alternator. They need to do a software upgrade to show you when a system goes out. My 1992 Corvette show you when there is a problem. Pathtic support on the part of General Motors.
