    I would suspect someone has wired power for the PTO from this fuse source and it is now shorted somewhere when engaged. That 5 amp fuse only powers your diagnostic port and ignition relays from the key switch. So follow A15 as best as possible and check for anything tapped into it that shouldn't be.
