## Discrepancy

WHILE WORKING AN MCO FOR AN APU REPORT TO NOT START, IT WAS FOUND THAT THE APU STARTER HAD EITHER BURNT, OVERHEATED OR CAUGHT FIRE.  THE STARTER CABLES WERE BURNT, AS WERE THE GENERATOR CABLES.  THE STARTER ITSELF WAS CHARRED AND DISCOLORED, AS WAS NUMEROUS WIRES AND WIRING HARNESSES.  REPLACED STARTER, CABLES, BATTERY CONTACTOR, AND AUX POWER RELAYS
