Electricly challenged...Help!

So i followed battery to starter,power.starter to big stud on starter relay,power.2b runs here aswell as my pink ignition feed.Pink ignition feed has power but 2b does not at the fuse block. Both are fuseable links. I stripped the insulation back on 2b after the link and ran a jumper from the battery. EVERYTHING WORKS.Car fired up and ran.headlights and tail lights work.Blinkers and radio do aswell.So two questions can a fuseable link go bad on the inside of the insulation and can i just use a replaceable fuse in its spot.
