## Discrepancy

(CAN) CLIMBING THROUGH 10,000 FEET, THE GPS REBOOTED & FLAGGED ON THE EFIS, SHORTLY AFTERWARDS & ELECTRICAL BURNING ODOR COULD BE DETECTED.  THE AIRCRAFT RETURNED.  REMOVED THE GPS FROM THE AIRCRAFT & COULD SMELL AN ELECTRICAL BURNED ODOR.  NO PHYSICAL DAMAGE TO ANY CIRCUITS OR WIRING WAS FOUND INSIDE THE UNIT, BUT WHEN THE UNIT WAS HOOKED UP TO A TEST BOX, IT AGAIN EMITTED AN ELECTRICAL ODOR.  A REPLACEMENT GPS WAS INSTALLED IN THE AIRCRAFT WITH NO FURTHER FAULTS.  THE UNIT IS BEING SENT FOR TESTING & FAULT ISOLATION.
