Burnt 7.3L UVC Connector

Another issue with 7.3L Power Stroke under valve cover harnesses is over heated and burnt up glow plug terminals in the pass though. In most cases the damage starts in the cylinder head side where most of the damage is however in some cases the engine harness is also damaged. Typically electrical circuits fail where high resistance is located such as the UVC plug however shorted glow plugs are thought to cause this by increasing the current draw on the circuit.
