## Discrepancy

(CAN) IN THE MIDDLE OF COMPLETING TASKS FOR THE APPROACH, THE AMBER EXTINGUISHER DISCHARGE LIGHT BECAME STEADILY ILLUMINATED.  IN THINKING IT WAS A ZONE FIRE LIGHT, ACTIONS WERE TAKEN TO COMPLETE THE ENGINE FIRE AFTER BSEC MEMORY ITEMS. THE ENGINE WAS SHUTDOWN IAW THE QRH AND AN UNEVENTFUL SINGLE ENGINE APPROACH TO CIRCLING AND LANDING WAS MADE.  MAINTENANCE INVESTIGATION HAS FOUND THAT THE WIRING TO THE DISCHARGE LIGHT HAD BEEN CHAFED THROUGH AND MOST LIKELY SHORTED TO TURN THE LIGHT ON.  WITH FURTHER INVESTIGATION, IT IS BELIEVED THAT THE WIRING WAS CHAFED DURING MULTIPLE RE AND RE`S OF THE PANEL THAT THE LIGHT IS MOUNTED TO.  WIRING HAS BEEN REPLACED AND SYS CHECKED SERVICEABLE.
