Are those wires soldered into the fuse holder? Soldering in that wire to the fuse holder looks like work.

If was going to do that kind of repair work I would have just cut the wires from the fuse holder, stripped and twisted them together. No need to find a piece of wire and the hassle of soldering the wire onto the fuse holder.

I am always surprised how much effort people will spend to fix something incorrectly. Using parts you have on hand to make something work is one thing, but soldering in jumper wires into the fuse holder just makes no sense at all.
