## Discrepancy

PDX - AFTER PARKING, STARTED APU.  IT MADE A GROWLING NOISE DURING START.  GEN WOULD NOT COME ON.  SHUT APU DOWN.  INSPECTED APU AND FOUND STARTER/GENERATOR HANGING DUE TO START/GEN CLAMP FAILURE.  FOUND APU B+ PWR FEED CABLE TERMINAL END BROKEN.  FAB AND INSTALLED OF NEW B+ PWR FEED CABLE.  REMOVED AND REPLACED APU START/GEN PER 24-33-01-000-801, AND 24-33-01-400-801.  INSTALLED SERVICABLE APU START/GEN CLAMP.  C/W OPERATIONAL TEST OF THE APU 28V DC GENERATION SYSTEM 24-33-00-710-801.  CHECKS GOOD.  NO DEFECTS NOTED.  RETURNED TO SERVICE.
