What causes alternator diodes to fail

Overheating, overloading, vibration and mechanical stress are the most common causes of alternator diode failure Alternator diodes are essential components that convert the alternating current (AC) produced by the alternator into direct current (DC), which is used by the vehicle’s electrical system. Although diodes are generally robust and long-lasting, they can fail for several reasons: Overheating is what kills alternator diodes Alternator Diodes are sensitive to temperature, and excessive heat can cause them to fail prematurely. Overheating can occur from a failing or faulty voltage regulator, poor air circulation around … Read More
