## Discrepancy

(CAN) WHILE INVESTIGATING A RADIO MASTER SWITCH MALFUNCTION, AVIONICS MASTER WOULD NOT TURN ON RADIOS UNLESS THE CONSOLE WAS TAPPED ON THE SIDE, A BURNT/OVERHEATED WIRE WAS NOTICED UNDER THE RADIOS AT THE BOTTOM OF THE GENEVA CONSOLE. WHILE REPAIRING THE WIRES IT WAS DISCOVERED THAT IT WAS LOOSE AND HAD OVERHEATED BURNING THE CONNECTOR. NO EVIDENCE OF ARCING AGAINST THE CONSOLE COULD BE FOUND. THE WIRE WAS REPAIRED A NEW END WAS CRIMPED ON AND THE AIRCRAFT WAS RETURNED TO SERVICE.
