Blowing fuses

I have no idea were the problem is, so I was hoping some of you guys would have some insite. My gauge cluster is not lighting up and the tail lights are also out. I keep on blowing 10amp tail light fuses under the hood. My tail lights still light up when I hit the brakes or use my turn signals. I put a 30amp fuse in and the cluster and the tail lights lit up just a little bit. I can not find any other blown fuses or grounded exposes wires so I have no idea if it is something incredible simple but who knows.
