Alternator or something else?
So last November the battery light came on in my TSX along with a high pitched whirring noise. Took it to a mechanic friend who said the alternator was bad and he replaced it. About a few weeks ago(5 months later) my battery light is starting to flash off and on occasionally while I'm coming to a stop or slowing down. Doesn't seem to every come on while accelerating. Mentioned it to my mechanic and even though the voltage outputs were good he replaced the alternator for free just to be safe. After about a week the light will randomly flash again while I'm stopping or slowing down. He said my battery is still good but is there something else that could be causing this? Could my car just not like the brand of alternator. He uses a rebuilt alternators from Carquest.

Also possible to have a slipping bushing in the crankshaft pulley/harmonic balancer. The rubber bushing gets loose and outer pulley slips instead of driving the accessory belt. Check is to make a radial mark across the face of the crankshaft pulley assy. If marks get displaced from each other the bushing is slipping.
good luck
