Alternator: what it does & when to replace it
The alternator charges the battery and powers the electrical system while the engine runs. Failure signs include a battery warning light, dimming or flickering lights, dead battery despite a recent replacement, a whining or grinding noise, or a burning-rubber smell. A failing alternator will eventually leave you stranded once the battery drains. Replacement is a moderate-to-advanced DIY job — access and serpentine-belt removal vary a lot by vehicle, and some require removing other components first. Have the charging system tested before replacing, since the battery or belt is sometimes the real culprit.
