## Discrepancy

ATTITUDE INDICATION SHOWS 5 DEGREE BANK IN LEVEL FLIGHT AND LT MFD AHARS APPROX 1 DEGREE EVERY 20 SECONDS.  FLIGHT DIVERTED TO KORD.  AIRCRAFT REMOVED FROM SERVICE.  REMOVED STBY ATTITUDE INDICATOR TO FOM, CHECKED FOR VOLTAGE AT CONNECTOR P1FD PIN A SHOWS 27 VDC.  CHECKED FOR GROUND AT CONNECTOR P1FD PINS B & E, BOTH SHOW 0.56 OHMS.  NO OBVIOUS DAMAGE TO CONNECTOR OR PINS.  REINSTALLED STBY ATTITUDE INDICATOR (CONT ON BLK 4) PER CRJ 200 AMM 34-23-01.  PERFORMED OPS CHECKS, OPS CHECKS FAIL. STILL SHOWS 5 DEG LEFT BANK.  NEEDS FURTHER TROUBLESHOOTING.  MX IN PROGRESS.
