DSPCivic

I have a 1994 Honda Civic Ex Coupe and it used to blow the fuse for the cluster lights, tail lights, and the corner lights. I replaced it a few times and then everything was fine. It blew again the other day and my cousin put a 30 amp fuse in the 10 amp spot and it blew again. Now none of the parking lights work, but the headlights still do. I tried looking for wires that were corroded or disconnected and found nothing. I went through with a test light and I have power from the switch and all the fuses and what not are working and have power. I lose the power somewhere between the box and the tail lights. I checked all the wires for my system and no wires are touching anything they aren't supposed to and they all are tight. I also checked if there was a short somewhere around the fused box and it didn't trip anything. Short of getting a new computer for it I can't think of anything. Any help would help.
