## Discrepancy

AFTER INSTALLING REPLACEMENT FUEL QUANTITY GAUGES AND TRANSMITTERS PER SK152-21A, THE TRANSMITTERS COULD NOT BE CALIBRATED, THE GAUGES READ FULL WITH TANKS LESS THAN HALF FULL.  THERE IS A RESISTOR, PN 20 OHM 5W, INSTALLED BY THE FACTORY, AT THE TRANSMITTER, ON THIS S/N AIRCRAFT.  THIS RESISTOR MUST BE REMOVED FOR THE NEW SYSTEM TO OPERATE PROPERLY, BUT IS NOT CALLED OUT IN THE INSTRUCTIONS PROVIDED WITH THE KIT.  A CALL TO CESSNA'S TECHNICAL DEPARTMENT CONFIRMED THIS.
