Problem solved!
Very strange>Test first fuse with meter and it's ok., but won't work>
change another (tested on meter, that's ok.), but won't work>
third tested fuse, and everything works ok.?!?!?
All so testing fuses with another meter and it shows too, that those are ok.
Those found their self at the garbage can..

So, main thing, that everything works.
Hint: Test on duty your spare fuses, that those really works. Not so nice to find out at
the highway, that those aren't ok...
Thanks for tips!
