I opened my guitar and there were no cables wrong or not attached. I did check the diagrams and on this website and compared and nothing was wrong. I tried some things like changing two cables so that the position 2 and 5 changed. In the normal 2 position, the sound I created was that of position 5 and vice versa and now it was position 5 who was broken!!!
So it is NOT the switch, in my opinion.
The Humbucker and the singlecoil, apart, work good. It must be that the coil tapping doesn't work?
