## Discrepancy

(CAN) DURING CRUISE, RIGHT HAND DC GENERATOR WENT OFF-LINE AND COULD NOT BE RESET.  MAINTENANCE INVESTIGATION REVEALED THAT VOLTAGE REGULATOR WAS REGULATING AT A HIGH VOLTAGE RATE AND COULD NOT BE ADJUSTED.  THIS RESULTED IN NR 1 DC GENERATOR TAKING MOST OF THE LOAD AND KICKING NR 2 GENERATOR OFF-LINE.  DEFECTIVE VOLTAGE REGULATOR WAS REPLACED.
