What was found
RT CENTER BOOST PUMP OVERRIDE CB POPS ON P6-4 PANEL. WIRING DAMAGE IN THE RH WHEEL WELL AS A RESULT OF ELECTRICAL ARCING. THE EVENT OCCURRED DURING A "C" CHECK VISIT WHEN TECHNICIANS WERE PERFORMING A ROUTINE INSULATION RESISTANCE CHECK OF THE FUEL PUMP. ANALYSIS OF THE DAMAGE REVEALED THAT AN UNUSUALLY SHARP BEND IN THE HARNESS SERVICE LOOP DETERIORATED THE PROTECTIVE INSULATION. THE EXPOSED CONDUCTORS ARCED TO THE SURROUNDING STRUCTURE CAUSING SEVERAL WIRES TO BE DAMAGED. DAMAGED WIRING WAS REPAIRED AND/OR REPLACED.
