## Discrepancy

(CAN) DUE TO A RECENT SHORTING AND MELTING OF THE CLOCK WIRE IN A LIKE PRODUCTION AIRCRAFT.  THE CLOCK WIRE WAS INSPECTED FOR THE PRESENCE OF A CIRCUIT PROTECTIVE DEVICE AND NONE WAS FOUND LEAVING THE CLOCK WIRE HOT FROM THE BATTERY SWITCH AND ULTIMATELY THE BATTERY.  AN IN-LINE FUSE WAS INSTALLED AT THE BATTERY SWITCH.
