## Discrepancy

(CAN) PILOT REPORTED LT PROPELLER HEAT AMPERAGE INDICATING "LOW".  UPON FURTHER EXAMINATION/TROUBLESHOOTING, MAINTENANCE DISCOVERED THE PROP HEAT WIRING HARNESS HAD NO PROTECTIVE SHEATHING INSTALLED. WITH NO PROTECTIVE SHEATHING , THE WIRE RUBBED AGAINST THE SPINNER AND CAUSED THE HARNESS TO ARC AND BURN A HOLE THROUGH THE SPINNER. SPINNER WAS DEEMED UNREPAIRABLE AND A NEW SPINNER WAS INSTALLED. THE WIRING HARNESS WAS REPAIRED AND INSTALLED SECURELY WITH PROTECTIVE SHEATHING TO PREVENT RE-OCCURRENCE.
