"at night headlights dim when turn signals on at idle Tech line #877117 checked charging system battery OK called Tech line Removed #2 pin white green wire from connectorC131 fixed problem."

"Found virtually every load in the vehicle receiving varied voltage input when blinkers were in use. Inconsistent voltage causing any light to have a slight strobe or flash effect. Determined fault to be present in every circuit suggesting a charging system error. Examined the "ELD" (Electrical Load Detector). Found ELD supplying PCM with varying and inconsistent commands/inputs, thus forcing the PCM to constantly switch the alternator from high to low output, causing a vehicle wide condition. Suspect after market bulbs of varying and difference from stock resistance causing an average amperage draw slightly different than stock. The new average draw falls in a gray area of the ELDs logic mapping software, making it difficult /impossible for the ELD via PCM to correctly command high/low operation at idle. If loads are added/taken away, or RPM brought up, problem diminishes. Bypassed ELD to create an always high condition/command for the alternator. This will have zero adverse effects."
