Hi , I appear to be getting some faults on the electrics on my 2012 Giulietta. I have sorted the tailgate opening button by repairing a broken wire in the l/h side gaitor. I now have a main beam headlight not working on the nearside. Lamp (bulb) is o.k and there`s 12volts at the connection - but this drops to zero when connected (yellow cable).Earth wire (brown) is earthing. Has anyone had this problem. Thanks for any help. Regards, Richard.
