Fatal Error during first Self Test
I just completed my build of a kit Prusa mk2
Tried to do a self check. Tested both fans ok but during the next step I lost all power.
Couldn't get it to power up again afterwards. Checked the 5A Fuse thats next to the 15A fuse and it is blown.
I now have to locate another fuse. .. . but will it just blow again? What happened? I checked all my wiring. . . . It looks good!
Thanks!!

Re: Fatal Error during first Self Test
IIRC that fuse is for the hot end. Any chance you confused the heater cables for hot end (5A) and build plate (15A)? If they're correct, there might be something with the wires.
If you have a ohm meter/multi meter. Try measuring the resistance of the heating block. It mustn't be short circuited.
