    Has anyone ever seen this before? Got home from work today and smelled something hot (electrical).
    Popped the hood to find smoke rolling out of the windings of the alternator. They are all discolored and greyish.

    Any ideas?

    Sounds like one of the diodes in the alternator went bad.

    Brushes are probably shot so there was lots of arcing to the commutator making lots of heat.

    Yeah, I'm not sure. The unit was only two and a half years old. Luckily it was under warranty.
