Failed alternator can cause "no charge" condition: GMC Sonoma Engine & Powertrain

Problem overview

The alternator may fail, causing a "no charge" condition. An internal bearing may also fail and cause an abnormal noise. If the vehicle is driven too long with a failed bearing, the alternator may stop turning, which can cause the serpentine belt to break or the engine to stall and not turn over.
