Quoted from Tom65:Is this plug on the right position?
No
It should be on J2.
The Connector on J15 received 12V with reversed polarity. Don't know if it blew something.

Quoted from DumbAss:If I read the schematic it looks like it's ok.
J2 is 180º rotated relative to J15 and J16.
Seen by the silkscreen, +12V should be left and GND on the right side. This means that the connector on J16 (in the picture post#12) is the one that comes from the powerboard and carries the power and must go to J2 !
And the connector on J15 (correct gry-yel on left side) is now receiving 12V with reversed polarity.
If something on this powerline has a pcb with polarity sensitive electronics ( steppermotor driver in backbox ?) it could have caused to blow the fuse on the powersupplyboard for the 12V,......this is also where the +5V is derived from.
