Hey! So I know I have an alternator problem but maybe the "things" that happened to me will spark an answer from you.
So while driving I got the LOW BATTERY warning sign... Came home, parked car and thats that. Next day I go to my car, sit down and drive off (No Low battery error). Was driving around for about half an hour before the warning came back on and eventually my car just shut down. So fast forward I recharged my battery at home, put it back in the car, started, checked voltage and I was getting 14.2! Great all is good right?... No.... I shut the car down, started again, booom the Low battery thing came on again, went to check voltage and its ~12.5 and dropping, so that means the alternator doesnt work again... I know many tests can be done to determine it better but Im pretty bad mechanically... So my question kind of is. What can cause the alternator to work sometimes and then stop working when I start it the next time. Are the most likely culprit wiring? Or a fuse? Or just the alternator somehow managing to work "half" of the time because the brushes have worn out or something like that. Any suggestions would be welcomed( or how to do tests to determine)
