Good morning. I replaced my Battery and Alternator yesterday due to my truck popping up this alert. I used my blue tooth obd2 and the car scanner app.The previous alternator was give me 11.1v even when driving on the freeway. Now with a new battery and alternator I’m getting 13 to 14.05 volts on average. At 6:20am I turned on the trucks AC and saw it dropped down to 12.2v but went back up when I drove on the street to the freeway 13+ volts. I turned off the AC at 6:25am. When I went to some stops, I let it idle and the Charging System now alert popped up. You can see around 6:30am and on, I did 4 stops and I see that my volts drops as low as 12.2v without AC running. What else can I do to fix this?
