## Discrepancy

(CAN) WIRE CHAFING BETWEEN THE 26 VAC BUNDLE FOR INSTRUMENT LIGHTS AND COMPASS SYSTEM WIRE BUNDLES RESULTED IN A ELECTRICAL SHORT AND SUBSEQUENT LOSS OF PILOT INSTRUMENT LIGHTS AND THE C-14 GYRO SYCRONIZER FOR THE COMPASS SYSTEMS.  INVESTIGATION REVEALED THAT WIRE BUNDLES WERE NOT ROUTED CORRECTLY AND WERE THUS RE-ROUTED CORRECTLY.  A NEW C-14 GYRO WAS INSTALLED AND ALL SYSTEMS ARE SERVICEABLE.
