## Discrepancy

(CAN) AIRCRAFT PERFORMED AN AIR-RETURN DUE TO THE #1 DC GENERATOR CAUTION LIGHT ILLUMINATING IN CRUISE. THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE MAINTENANCE CREW REPLACED THE CONTACTOR UNIT (P/N: 1096224-2) AS PER AMM 24-31-31 BUT THIS DID NOT RESOLVE THE ISSUE. THE DC STARTER GENERATOR (P/N: 1152106-3) WAS THEN REPLACED AS PER AMM 24-31-01 AND THIS RESOLVED THE ISSUE.  THE AIRCRAFT RETURNED TO SERVICE WITHOUT ANY FURTHER INCIDENT. (TC# 20190516021)
