## Discrepancy

UPON INSTALLATION OF A REPAIRED CABIN PRESSURE RATE CONTROLLER IT WAS FOUND THAT THE AC WOULD NOT TEST OR PRESSURIZE ON THE GROUND.  AFTER CHECKING THE ATTACHING SYSTEMS THE CANNON PLUG ON THE CONTROLLER WAS DISCONNECTED AND INSPECTED.  AT INSPECTION IT WAS FOUND THAT THE CANNON PLUG PINS WERE PUSHED BACK FAR ENOUGH AND ALSO BENT SO AS NO CONNECTION COULD BE MADE. IT WAS ALSO NOTED THAT ON THE INSIDE OF THE CANNON PLUG THE  INSULATION ON THE WIRES HAD NOT BEEN STRIPPED BACK.  THE WIRES WERE JUST CRIMPED TO THE PINS AND PUT IN TO THE CANON PLUG.
