Detailed Description

Built for Cadillac DeVille, Eldorado, and Seville charging-system service, the WAI 8127N alternator is specified for vehicles using a serpentine belt drive, internal regulator, and clockwise rotation. The included pulley and 6-groove configuration support direct replacement needs on listed applications, while the 140-amp output helps maintain stable charging performance under accessory demand. This part number 8127N also cross-references BBB Industries 8127-11 for the same application.

Common Replacement Reasons

• Battery warning light or charging-system fault
• Low charging output at idle or under load
• Dim lights or electrical instability
• Noise from a worn alternator assembly
• Failure on Cadillac DeVille, Eldorado, or Seville applications

Installation Notes and Tips

Verify the vehicle’s build date and heated-windshield configuration before ordering, since fitment is limited to the listed Cadillac applications. Confirm pulley style, rotation direction, regulator type, and connector match the original unit before installation. The part number 8127N is also associated with OE references 10463377 and 10479995.
