Fleece Performance Charging Circuit Harness for Ford (2011-16) 6.7L Power Stroke

Problem Overview

COMPLAINT: Charging circuit MIL illuminated intermittingly or continuously on the truck dash.

CAUSE: Damaged, stressed, chaffed, or broken charging circuit sense wires in the OEM harness that are routed from the Powertrain Control Module (PCM) to the alternator resulting in an intermittent or continuously low voltage reading to the PCM.

DESCRIPTION: Due to the routing, exposure, and general lack of protection on the small charging circuit sense wires that are routed from Powertrain Control Module (PCM) to the alternator it is common for wire damage to be experienced. The routing of the OE harness is cumbersome and extremely difficult to replace and diagnose. Images below show the routing location of the wires in the plastic channel located on the underside of the engine as well as exposed in sections between the channels. These locations are also subjected to vibration and harsh weather and environment, resulting in shortened service life. Images of the routing location of these wires on the underside of the engine are shown below.

FIX/SOLUTION: The Fleece Performance Charging Circuit Harness is a drop-in replacement to replace a failed factory harness causing an intermittent or illuminated charging circuit MIL on the dash. The harness installs directly in-line with factory connections with no cutting or splicing and allows you to reroute the alternator connection along the top side of the engine, avoiding the unprotected channel routing on the underside of the engine.
