Mazda 5 Protege 2003 automatic battery light on
 

Hi all
3 Months ago I got an big issues with my Mazda Protege 5 2003, the speed jump directly from 0 tp 3, Battery, check engine lights on, the alternator doesn't charge well the battery, light flickering, and the engine RPM not stable at all time.

Well, the mecano said is the alternator goes bad, we bud a new brand, the problem still.
Then, he said is your PCM, I bud a new brand, the problem still, and nothing changed.

Could you please help me if someone had the same experience.

Thanks.
