Finch Alternator & Starter Rebuilders popularity statistics

Remanufactured parts meet Finch approved service part requirements and are made from previously used components in a process that involves disassembly, inspection, cleaning, update of software and replacement of parts as appropriate, testing, and reassembly. * Refurbished parts meet only the highest standard/s/ developed by Doug Finch and ultimately approved service part requirements and are previously used parts that are inspected, cleaned, tested, and repackaged.

Rectifier failure is one of the primary causes of alternator failures, most often caused by diode malfunction
Finch Alternators and Starters  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
Finch Alternators and Starters  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
Finch Alternators and Starters  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
Finch Alternators and Starters  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
Finch Alternators and Starters  brushes are 100 % and durability tested for performance and reliability
