You've got issues.
1. The positive wire doesn't need fuses to work - it just needs fuses to protect it from a short.
2. The fuses shouldn't blow unless there was a short in the wire - that's telling you something.
3. Never, never, never, never! (can we repeat that again? Never!) bridge a fuse with a piece of wire, "just to get it to work". That little thing is telling you something - it's saying that you've got other problems to deal with first! I have heard of countless cases where a minor problem was made worse by someone "just trying to get it to work" and bridging a fuse.
