Question about 2003 BMW 325
My husband has replaced the battery in his 1990 BMW 325I, but the battery keeps dying on us. He says it isn't the alternator, because the car wouldn't turn over if it was. What else could it possible be?
Hi and welcome to FixYa,
Initially, it could be the alternator or more specifically the voltage regulator inside the alternator. The function of the alternator is to produce the necessary charging voltage to replenish the charge of the battery. This voltage is then funneled and controlled by the regulator. Of course even if the alternator/regulator is good, there could be other possible reason(s) why the battery looses or is not charging such as loose wire/connector/terminals or a partial electrical short/fault draining the battery when parked.
To crank (turnover) the car's engine, a starter is used.
Good luck and Thank you for using FixYa.
