Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- Higher than expected voltage problems are most likely caused by bad voltage regulator. The voltage regulator is part of the alternator.
