What was found
(CAN) WHILE TROUBLESHOOTING A SNAG FOR A COMM 2 CIRCUIT BREAKER TRIPPING, THE MECHANIC FOUND THE POWER WIRE CHAFED ON THE EDGE OF THE LIGHTING MODULE. THE WIRE WAS CHAFED ALMOST COMPLETELY THROUGH. THE WIRE IS DIFFICULT TO SEE FROM THE INSPECTION AREA BUT NOT IMPOSSIBLE. THE CIRCUIT BREAKER POPPING HAD OCCURRED BEFORE AND WAS ASSUMED TO BE CAUSED BY THE RADIO HAVING AN INTERNAL ISSUE. THE WIRE WAS REPAIRED AND THE RADIO TESTED WITH NO FAULTS FOUND.
