THE PLT EXPERIENCED SMOKE IN THE COCKPIT WHICH HE STATED CAME FROM UNDERNEATH THE INSTRUMENT PANEL. ACCORDING TO THE PLT, THE TRIM TAB SWITCH BECAME INOPERATIVE, THE FLIGHT CONTROLS BECAME 'HEAVY' AND THE WX RADAR CIRCUIT BREAKER POPPED EVEN THOUGH THE RADAR WAS OFF. THE PLT STATED THE SMOKE EVENTUALLY STOPPED AND HE CONTINUED TO THE DESTINATION AND LANDED WITHOUT INCIDENT. EXAMINATION OF THE ACFT REVEALED THAT INSIDE THE RIGHT WING, NEAR THE ROOT SECTION, THE WIRES FOR THE NAV LITE, STROBE LITE, AND FUEL QUANTITY TRANSMITTER SHORTED AND BURNED. THE WIRES WERE NEXT TO A FUEL VENTLINE THAT HAD BEEN CHANGED. REVIEW OF MAINTENANCE RECORDS DISCLOSED THAT ABOUT 3 YRS AGO A RADAR POD AND RADOME WERE INSTALLED WHICH INVOLVED ROUTING OF WIRES THROUGH THE AREA WHERE THE SHORTED WIRES WERE LOCATED.
IMPROPER MAINTENANCE RESULTING IN THE ROUTING OF WIRE WHICH CAUSED AN ELECTRICAL SHORT AND INFLIGHT SMOKE.
