I am having a slight problem... my flb fuse is blowing everytime its replaced.... the flb fuse to my understanding is the fuse to the fuse box. electronical changes i have done, took off the apexi v-afc off, connected all the wires back... my alternator was not charging at the correct charge... took the alternator out, found out it was a bolt to the negative that was broken. replaced it and had this problem ever since. nothing work but the horn....i guess it could be the alternator needing to be replaced totally on some loose connection before the fuse box... some input guys...please?

I need the car for work by monday

Fuses only blow if you have a short!(power to ground)
Recheck all connections (proper place) but mostly the alternator!
Happens with switch off?
