## Discrepancy

(CAN) ACFT TOOK OFF AND AFTER A SHORT PERIOD OBSERVED PROBLEMS WITH THE PRESSURIZATION, NOT PRESSURIZING, AND ELECTED TO SWITCH TO MANUAL AND NOTED THERE WERE NO PROBLEMS AFTER THAT.  A SHORT TIME LATER DURING SOME TURBULENCE A LT AC BUS LIGHT ON THE ANNUNCIATION PANEL SO THEY SWITCHED TO THE 3RD INVERTER.  AT THIS POINT THE CREW STARTED TO SMELL SMOKE, ELECTRICAL IN NATURE, ALTHOUGH THEY DID NOT SEE ANY. THEY ATTEMPTED TO ISOLATE THE SMELL AND ALTHOUGH DID NOT ISOLATE IT BY TURNING C/B OFF THE SMOKE SMELL DID START TO DISSIPATE.  AFTER MX DID THEIR INVESTIGATION THEY FOUND A PAPERCLIP IN THE RT C/B PANEL.  ONCE THE PAPERCLIP WAS REMOVED ALL SYS FUNCTIONED NORMALLY.
