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 sealsRotors 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 coatingSlip 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 outputBrushes: 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 reliabilityFunction & Signs of WearFind out more about ACDelco Professional Remanufactured Alternators and how they fit into the Starting and Charging System with the product facts below.Function: Provides power to the vehicle's electrical systems and charges the battery while the engine is runningSigns Of Wear: Engine doesn't turn over, loss of battery power, some loss of electrical power (dimming headlights, etc.), alternator warning light illuminates What It DoesThe Starting and Charging System starts the engine, maintains the battery's charge and provides power to the electrical accessories while the engine is running.Service & Maintenance Remanufactured with new solenoids and regulators.
