I know some cars charge at 13.8volts when the car is warmed up. However, it seems that on hot days and sometimes randomly my voltage drops to 12.8 or 12.2 at idle with no music on. Maybe my alternator going bad? kinda hope so. So i have an excuse to get a HO alt. Car is 98 saturn sl1 btw. Should I get it tested at autozone or wherever?
