• 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

Inseguro su Alternador es la Problema?

Cuando la batería se agota, el estado de la batería y del alternador son dos de las primeras cosas que hay que comprobar. Sin embargo, no asuma que si la batería está bien entonces el alternador debe estar mal y ser la causa del problema.
