fuse not blown, want to see if bypass will fix it, then it would be a faulty holder..............
Nope. Not a good idea. What if the holder is faulty because of overcurrent? There are three much safer ways to do this:
1. Do what @Chicken lights suggested. Remove the existing fuse and use an in-line fuse to jumper the connections.
2. Physically disconnect one end of the wiring someplace remote from the fuse and use a continuity tester on various parts of the circuit and in particular the fuse and fuse holder.
3. Use a multimeter to test for voltage at both sides of the fuse, and across the fuse.
