My turning lights just stopped working, what can it be?

I have checked the fuse-boxes, but cannot find the fuse for the turning
lights, where?

..

I think there is something generally wrong with the el-system, as
earlier the automatic daylight running lights stopped working. Then my
break-lights stopped functioning (also cannot find and fuse for it..?).

And the battery voltage is varying between 13,5 - 14,3 when motor
running, and 11,6 when motor is off. Should I do anything about this?
