Alternator Rectifier

Alternator diodes on the rectifier can fail due to harsh power demands. Your alternator produces AC current, which must be converted to DC current through the rectifier. When it fails, that current no longer flows. Electrical parts working below full strength, not working at all, or interference in your electrical systems could mean a bad alternator or rectifier. Things like dim lights and engine stalls are also common symptoms. These problems can range from frustrating to dangerous. O'Reilly Auto Parts stocks quality charging system parts for many vehicles.
