Q: Alternator making noise

asked by on February 16, 2016

The alternator is making noise. I have changed the battery several times, but after some time, the battery doesn't charge.

The charging system would need to be checked to see if it is charging, or killing the battery; the alternator is most likely the cause. I recommend that you have a mechanic, such as one from YourMechanic, come by and diagnose the cause of your battery not holding a charge.
