Have the internal lights and the radio stopped working too? I've the 2002 model Pug Partner and they're all run off the same fuse. I could see which one was gone just by looking at the fuse panel though,.. the fuses are kinda transparent on top, so I just looked for the melted one! You can get a split charge relay off ebay for about £10, and a second battery in the boot for another £30 odd,... it'll save a lot of problems in the long run,....
