Best Answer

Exposure to the rough underhood environment combined with time will find something to corrode and cause a failure eventually, too. A high quality alternator can reduce, but not eliminate, that factor.

Naturally stressing the alternator with unsually high demand for current causes more electricity to be generated, which heats the components.

When it runs too hot, its pretty much chance which one goes first - the insulation between the wires in the winding, or the rectifier diodes.
