Is 14.6 volts too high for the alternator? (2024)

Is 14.6 overloaded?

14.8 volts would be a problem (there could be fluid or corrosion in the battery) and 15 volts would be a real problem, however14.6 is ok. Less than 14.3 would be a "weak" alternator or regulator. Much less than 14.2 at fast idle is bad wiring, a bad alternator or regulator, or a bad connection or fuse.
