CHEVROLET TRAILBLAZER ALTERNATOR PROBLEM

2004 Chevrolet Trailblazer • 110,000 miles

The alt light glows dim all the time. Key on eng. On, key off eng off does not matter. Alt and battery were replaced in last 3k miles. Charging system seems to be working fine. Any idea whats wrong and what to fix.

Check all the connections. If they are ok, you have a bad diode in the alternator. Return to the shop and have it replaced under warranty
