Charging problem
I have trouble sourcing the problem and was hoping someone could help.
Long story short, I recently noticed signs of the alternator not charging (there was NO WARNING LIGHT on the dash). Checked the voltage on battery with the engine running and confirmed there was a charging problem (12.2V)
I rebuilt the alternator- new regulator, brushes and bearings. Now, I read 14,5V which seems to be fine, but only for 1-2 minutes after starting the car. I also get intermittent BATTERY NOT CHARGING message even at the beginning when the alternator is charging properly. After 1-2 minutes the voltage drops to 12V.
Has anyone experienced anything similar or has an idea what might be the reason ?
Don't know if this is related, but at the same time I noticed lack of charging, a loud whining noise (my car is NOT SC) in the engine appeared ( hard to locate precisely). Suspected alternator bearings and then the water pump, but after changing both the noise is still present.
Any help would be much appreciated.
