From this picture, It's clear that my opus 150 is dead

Okay,I just finished submitting my ROMA at OPUS's website but I'm more concerned about it not happening again. Now mg opus was blowing about a fuse a week for about a mouth now. Not sure why though.

My setup is simple. Got a yellow top in the trunk connected to the car's electrical systemthrough a relay which cuts off during cranking and while the car is off.

Any ideas what could be causing this?
