N80017 EXPERIENCED ENGINE TROUBLE AND SHUT DOWN THE LEFT ENGINE ENROUTE FROM AMARILLO, TX. LATER, BECAUSE OF ELECTRICAL PROBLEMS THE PILOT SECURED ALL ELECTRICAL EQUIPMENT EXCEPT THE NO. 2 RADIO, TRANSPONDER AND ROTATING BEACON AFTER LANDING, THE PILOT TAXIED CLEAR OF THE RUNWAY BUT COULD NOT TAXI FURTHER DUE TO LACK OF DIRECTIONAL CONTROL. N130L WAS RETURNING FROM LUBBOCK, TX. AFTER LANDING AT DALLAS-FORT WORTH. N130L PROCEEDED TO CROSS RUNWAY 31L AND REDUCED POWER TO TAXI TO THE RAMP. AT THIS TIME HE NOTICED SOMETHING PROTRUDING TOWARD THE LEFT SIDE OF THE TAXIWAY AND APPLIED BRAKES. AS HE REALIZED THE OBJECT WAS AN UNLIT AIRCRAFT WING HIS RIGHT PROPELLER CAME IN CONTACT WITH THE AFT OUTBOARD SECTION OF N80O17'S WING. THE PILOT OF N130L WAS NOT ADVISED OF THE POSITION OR CONDITION OF N80017 BY GROUND CONTROL WHEN CLEARED TO TAXI TO THE RAMP AREA.
