## Discrepancy

WHILE PREPARING ACFT TO INSTALL AEROSPACE LIGHTING CORPORATION'S PROTECTED POWER SUPPLIES IN THE CABIN FLUORESCENT LIGHTING SYSTEM, AN INSPECTION OF THE HIGH VOLTAGE WIRING REVEALED A SHORT LENGTH OF WIRE THAT HAD BURNED INSULATION.  THERE WAS NO DAMAGE TO ANY EQUIPMENT OR STRUCTURE IN THE AREA.  A COMPLETE INSPECTION OF THE HIGH VOLTAGE WIRE SYSTEM UNCOVERED SEVERAL SPOTS WHERE IT APPEARED THAT HIGH VOLTAGE HAD ARCED BETWEEN 2 WIRES (BROWN PIN HOLES).  ALL OF THESE SPOTS WERE LOCATED WHERE THE WIRE HAD BEEN TIE-WRAPPED TOGETHER.  THE PROTECTED POWER SUPPLIES THAT ARE BEING INSTALLED WOULD HAVE SHUT THE SYSTEM DOWN IN THIS CONDITION.  AD 90-14-06 HAD BEEN C/W.  MFG P/N, MIL SPEC W-16878.
