ok guys,
i have checked everything. Here is what i learned so far:
my headlight switch (upper left) activate the pop ups when the light is turned on. When you turn off the headlight the pop ups are supposed to go down automaticly.
The switch works fine.
I took out the switch and disconnected the wire that feeds the downwards motion. Now the fuse stays ok and when i manually lower the popups they work good. the lights go on and they pop up.
When i switch them off the lights go out but the headlights stay up.
Now when i put ground on the wire for the downward motion, nothing happens. When i put 12v on the wire, the fuse burns, like it used to. The lights stay up.
So any suggestions to help me move further are very welcome.
Thanks in advance,
