How To Tell If A BMW Fuse Has Blown:

The BMW fuses have an exposed wire on the back of them. When the fuse blows that wire melts to disconnect the circuit so you can visually tell if a fuse is blown. It's a tiny wire so you have to look closely to see if the fuse has blown.

Fuse Size:

You can also use generic standard ATC fuses in lieu of the BMW factory fuses. (Not to be confused with Mini ATC fuses.)

To see if a generic ATC fuse is blown you need to pull the fuse to see if the wire inside of it has melted.

Direction:

The forward (left) side of the fuses is the input ("hot") side of each fuse.

Adding Fuses:

When I add electrical stuff to my K bikes I don't like adding in-line fuses because I think they're a ghetto way to do things. So I add a mini fuse block right next to the factory fuses:

Instructions on how to do this can be found at this link.

Adding Fuses To A K1, K100RS4V or K1100:

K1s, K100RS4Vs and K1100s have  empty fuse slots at the bottom that can be used for adding your own. Here's an example where I added three fuses to a K1100RS:

Instructions on how to do this can be found at this link.
