## Discrepancy

(CAN) JUST PRIOR TO ENGINE START AT AN OUTBASE, THE A/C APU SHUT DOWN ON ITS OWN.  GROUND EQUIPMENT WAS USED TO POWER AND START THE A/C, AND THE FLIGHT CONTINUED. AT THE TERMINATING BASE, MAINTENANCE PERSONNEL FOUND 2 WIRES AT THE APU THAT HAD CHAFED AND SHORTED AGAINST EACH OTHER. THE WIRES WERE REPAIRED AND THE A/C RETURNED TO SERVICE.
