• 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 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

• 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 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 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

Nicht sicher, ob die Lichtmaschine das Problem ist?

Wenn die Batterie leer ist, sind der Zustand der Batterie und der Lichtmaschine zwei der ersten Dinge, die überprüft werden müssen. Gehen Sie jedoch nicht sofort davon aus, dass, wenn die Batterie gut ist, die Lichtmaschine defekt sein muss und somit die Ursache des Problems ist.
