## Discrepancy

IN CRUISE, FLIGHT AT 6500 FT, THE NR 2 SERVO CAUTION LIGHT CAME ON.  OPENED THE SYNOPTIC PAGE AND FOUND ALL PRESSURE AND TEMPS NORMAL. HOWEVER THE 4 SERVO LIGHTS WERE YELLOW.  FOLLOWED THE EMERGENCY PROCEDURES CHECKLIST AND TURNED AROUND. AFTER A FEW MINUTES THE CAUTION LIGHT BEGAN TO GO OFF AND ON AND AFTER A MINUTE OF THAT IT WENT OUT AND STAYED OUT.  RETURNED FOR MAINTENANCE TO CHECK THE PROBLEM.
