Condor B763 near Budapest on Apr 1st 2014, electrical problem

A Condor Boeing 767-300, registration D-ABUA performing flight DE-2262 from Vienna (Austria) to Mombasa (Kenya), was climbing out of Vienna about 65nm southwest of Budapest (Hungary) when the crew requested to stop their climb at FL330 and divert to Budapest, they would check weather first. The crew declined any waypoint navigation but requested radar vectors accepting headings only, then requested a descent to FL160. While descending towards Budapest the crew requested to divert to Vienna and again requested vectors, not accepting any VOR or FMS waypoint assignments. The crew finally reported they had electrical problems and needed the emergency services upon arrival in Vienna. Budapest Center advised to expect runway 29 in Vienna, emergency services would stand by. The aircraft landed safely but overweight on Vienna's runway 29 about 25 minutes after requesting to stop the climb, emergency services checked the brakes upon arrival.
