## Discrepancy

ATTEMPTED TO START THE APU AFTER LANDING WHILE TAXIING & RECEIVED A RT ESS BUSS FAULT CAS & AN APU FAIL CAS, AFTER ENG SHUTDOWN.  THE RT BATTERY COULD NOT BE SHUTOFF.  FORCED TO DISCONNECT THE BATTERY CABLES. TROUBLESHOOTING FOUND THE RT AFT PDP DEFECTIVE & REPLACED IT WITH REPAIRED UNIT.  OPERATIONS CHECKS SATISFACTORY.
