hey everyone, my first time using this so i hope i say things right..

Im just interested in one fuse in particular thats located under the bonet, its like a small red fuse next to 3 round and one big rectangle fuse. My fuse melted recently after i bought the car so im thinking that it might be the wrong fuse, maybe too many amps or too less, im not too sure, its the amp that controls the ignition as well, so basically theres no power without this fuse. Any ideas on what amp / fuse it should be running?
Also how would i go about posting pictures of my cordia ?
