ACDelco Remanufactured Alternators are available for most vehicles on the road today and are 100 percent tested after remanufacture:
Rectifiers:- Rectifier failure is one of the primary causes of alternator failures, most often caused by diode malfunction
- ACDelco rectifiers are 100 % electronically tested and replaced when needed
Bearings:- Bearings are always replaced with new
- Bearings are critical to alternator durability due to extreme lateral loads applied by the drive belt, in addition to excessive heat and vibration
- ACDelco alternators use only quality bearings with high temperature lubrication and double-lipped rubber seals
Rotors and Stators:- The heart of the alternator and its current-generating components, rotors and stators maybe subjected to excessive heat, which can deteriorate insulation and cause shorts
- ACDelco rotors and stators are electronically tested for proper performance, then sealed with a flexible secondary insulating coating
Slip Rings:- Slip rings must be in constant contact with the brushes, or uneven wear leading to failure can occur
- ACDelco slip rings are precision polished to help maximize electrical contact and consistent output
Brushes:- Brushes are always replaced with new
- Worn brushes interrupt electrical contact, shortening the life of alternators
- ACDelco brushes are 100 % and durability tested for performance and reliability
Performance and reliability testing includes; sound room tests, vibration tests and exposure to hot and cold rooms
 Not Sure Your Alternator is the Problem? When the battery goes dead, the condition of the battery and the alternator are two of the first things to check. However, do not assume that if the battery is good then the alternator must be bad and the cause of the problem.
