What Makes an Alternator go Bad

Several factors can contribute to the failure of an alternator. Here are some common causes:
Worn-out Bearings: The alternator contains internal bearings that allow the rotor to spin smoothly. Over time, these bearings can wear out due to heat and friction, causing the alternator to fail.
Faulty Voltage Regulator: The voltage regulator is responsible for regulating the electrical output of the alternator. If it malfunctions, it can either overcharge or undercharge the battery, leading to alternator failure.
Diode Problems: Alternators use diodes to convert alternating current (AC) into direct current (DC). If one or ...
