I removed the auto RCM now. It seems like the switch has bigger problems… when plugged in, I get 0 amps (actually sometime it show 0.02 amps for a split second, but most of the time 0 amps) and a black screen.
15V go up to the M92T36 (meassured at the cap very close to the IC).
Fuse seems ok, as I get 15V after it and on parts beeing connected to it like the M92T36.
