Morning all. First time user so forgive me. I have just purchased a 58 plate fiat bravo 1.9 multijet 120 dynamic from the auctions. on Tuesday it was running and driving fine however when I went to collect it on Thursday it had a flat battery and refused to start. I have replaced the battery however I still have no interior power. The interior light doesn't come on, the central locking doesn't work, the stereo and heater doesn't light up and the boot won't open however when you put the key in the ignition and turn the key the dash lights up and the display and it will turn over ok but won't start. Any suggestions as to what it may be would be greatly appreciated. I'm leaning towards a fuse or a relay problem but I have no idea which or where and I could be completely wrong. Please help!
