Review on Compatible Replacement DB Electrical ADR0215 Alternator for Chevrolet Silverado 1500 HD 2003, Silverado 1500 2003-2005, Express Vans 2003-2005 - 90-01-4705N, 90-01-4705, 1-2320-21DR, 8247N by Justin Olson

Inexpensive replacement but I am concerned about alternator quality control

Inexpensive replacement but there is a whistling noise at idle indicating alternator problems. Headlights and other electrical consumers become significantly brighter when accelerating or increasing engine speed when idling. I think the alternator will need to be fixed soon as I am an ASE and Michigan certified auto technician and have currently worked at a dealership for over 10 years.

Pros
  • Great for a small home
Cons
  • The list will go on.
