## Discrepancy

DUE TO WEATHER CONDITIONS AND LOSS OF WX RADAR, DECISION WAS MADE TO DIVERT THE FLIGHT.  WEATHER RADAR TRANSCEIVER TESTS RETURNED "NO FAULT FOUND".  TESTS FOUND WEATHER RADAR SCANNER HAD FAULTY AZ MOTOR AND THERMAL RESISTOR.   REPLACED WEATHER RADAR TRANSCEIVER AND WEATHER RADAR SCANNER. SHOP REPLACED THE AZ MOTOR AND THERMAL RESISTOR, AS WELL AS REBUILT AZ AND EL GEAR ASSEMBLIES, ON THE WEATHER RADAR SCANNER.
