## Discrepancy

ON CLIMBOUT WE NOTICED THE AIR DATA COMPUTER FAILED ALONG WITH NR1 DC GEN CAUTION LIGHT ILLUMINATED.  WE EXCUTED PROCEDURES IN ABNORMAL CHECKLIST, LIGHT EXTINGUISHED.  3 MINUTES LATER, LIGHT CAME BACK ON.  WE TURNED OFF THE NR1 DC GEN SWITCH PER ABNORMAL CHECKLIST.  WE REQUESTED RETURN TO AIRPORT WITH EMERGENCY EQUIPMENT STAND-BY.  WE LANDED SAFELY AND RETURNED TO TERMINAL WITHOUT INCIDENT.  FOUND NEGATIVE TERMINAL ON DC GENERATOR, BROKEN.  REMOVED AND REPLACED DC GENERATOR IAW MM.  AFTER REPLACEMENT OF NR1 STARTER/GENERATOR, OPS TEST OF NR1 ADC GOOD.
