NOTE: For troubleshooting information not discussed in this article, see CHARGING SYSTEM - GENERAL TROUBLE SHOOTING article in GENERAL INFORMATION.

Verify the customer's concern by operating the engine to duplicate the concern. Prior to performing any testing, check system for obvious faults or damage:

Battery case, posts, hold-down clamp, cables and connections.
Generator drive belt.
Generator pulley.
Faulty fuses and fusible links.
Loose or corroded connections.
Damaged wiring harness.

If problem cannot be readily located, diagnose by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
