Velcommen...
(that is the extent of any Norwegien I picked up from logger sports events years ago)
Electrical problems eh... tell us it isn't so...

Usually the ground conections. I've pulled the fuses and given the top and bottom contacts a cleaning with a dremel and fine sandpaper. The ground pods on the wheel wells...take them off and clean behind and the spade tangs.
From what I remember of Norway(37 years ago), some cool roads up north and wild roads down to the heads of the fiords.
There are a few here from the scandinavian countries.
Have fun
