Hello attentive Ford Mondeo Volk. I have a question : Maybe I’ll pick something up – why and so… I had a footroom lighting in the form of cold light cathode tubes. ( from the PC need ) with converter. That looked good (my nephew had the built-in ) and made sense there is no light back there and at night when entering the thing easier. Well – I got 4 of these tubes at Conrad incl 12 volt converter. Footroom Mondeo MK 3 — Footroom mountain ne – out and with two terminals the tube incl. converter on it ( voher measured because of +/- ) now the tube does not work, the next taken incl. new converter does not work either. Ok again in the house — on the plug power supply ( universal with 7,8,9,10,12 volts ) tried out goes from 8 volts to said 12 volts. Again in the Mondeo — on the cigarette lighter — does not go. Sometimes directly to the interior light in the sky – parallel to the bulb that shines even at this moment — also does not work. out of fun times the cooler to the cigarette lighter — goes and runs. Tube turn — doesn’t work. What am I doing wrong ???? I’m grateful for every tip Greetings helpless Andreas
