## Discrepancy

(CAN) AT CRUISE, BATTERY AND LEFT EMERGENCY AC BUS WERE PULSATING.  RESET BATTERY CHARGER CIRCUIT BREAKER, PROBLEM STILL EVIDENT.  CHARGING STOPPED COMPLETELY, VOLTAGE DROPPED TO 20 VOLTS.  AFTER STARTING DIVERSION CHARGING STARTED TO CYCLE FOR APPROXIMATELY 5 MINUTES, THEN PEGGED AT 50 AMPS AND BATTERY CHARGER CIRCUIT BREAKER TRIPPED.  LANDED OK.  REPLACED BATTERY CHARGER, BATTERIES, CIRCUIT BREAKER.
