What is your question?
Have replaced alternator 2x in the past month. When car is running without lights, AC etc, it charges battery fine. When lights or AC, etc are on, the energy to the battery drops.
Pardon me - it’s POWER PREMIUM. Suspect your present alternator is of lesser quality. Alternator output should be a TESTED using a volt meter at battery terminals. Good luck!
