I have an 01 v6 manual which I can't seem to diagnose voltage issues. I had the alternator rebuilt and tested plus I made sure my battery is in good working condition and bought a new serpentine belt. Everything is good but the way it's working is when I turn the car on it gives me a good 14+ volts output on the alternator. After driving for about two minutes the battery light will come on and I checked the voltage immediately giving me only 11.8 to 12.2 volts readout. I've checked all fuses and there is no electrical drain on the car at all. Had battery and alternator tested again and everything is fine. Replaced post connectors and I cleaned and tightened the grounds on the car.
Any ideas on how I can approach this or help would be appreciated.
