## Discrepancy

AFTER BOTH ENGINES STARTED, ATTEMPTED TO PUT THE NR 1 GENERATOR ONLINE,  BUT IT WOULD NOT GO ONLINE. JUST BLUE GEN OFF BUSS LIGHT REMAIN ILLUMINATED. THE NR 1 GEN SHOWED ZERO AMPS AND ZERO VOLTS.  ACFT GROUNDED.  REMOVED AND REPLACED THE NR 1 IDG IAW AMM 24-11-11. IDLE RUNS GOOD, OPS CHECKED NORMAL.
