04 civic, Speedo not working, Battery light on.

#1
Hey guys. I was driving and noticed the speedo wasnt working. the battery light and cel is on. I checked and sure enough the #4 fuse 10 amp under the dash, marked "alternator" is blown. I replaced it 4 times, and it blew each time when I started to drive. The main alternator fuse isnt blown. 2004 civic, boosted, however it is water and intercooled so it shouldnt be putting off enough heat to blow the alternator. It has 107000 miles. Only thing that pulls for the cel seems to be turbo/test pipe related, 02 sensor, high idle, air leak. can anyone help? none of the wires seem to be grounded..
