Bad Alternator Diodes at Brodie Purser blog

Bad Alternator Diodes. This usually is coupled with a fault in the voltage regulator. Therefore, never apply reverse polarity to the alternator. A bad alternator diode can cause issues such as dim lights, a dead battery, or trouble starting your car. A bad diode in the alternator is one of the most common causes of a bad alternator. If the diode shorts you will drain your battery when the engine is off. If the reading is below 13 volts, then it is likely that one or more diodes are faulty. 4,5/5    (2.291) If the diode goes open you will only lose some output and it won't. Diode failure can result in an array of electrical problems, from poor battery charging to malfunctioning systems and components. Another common cause of alternator failure due to one or more bad diode(s) within the rectifier, is reverse polarity. To diagnose the issue, you can use a multimeter to check the voltage output of your alternator. Bad diode in alternator symptoms. There are 2 ways a diode can fail, open or short. A bad diode can cause overheating in the alternator and cause electrical components to fail prematurely. Often a diode going out and a faulty voltage regulator go hand in hand.
