Short circuit on battery cables

[Andysufc0201]

Hi everyone
Just returned from a trip away where I managed to put battery leads on opposite terminals , we have a swift challenger sport 585 2013 , I no have no battery power to control panel or psu when off hook up , could this be a blown fuse and if so where would it be located ,have read somewhere that there's a yellow 20v hidden fuse on battery line
Regards
Andy

Hi...welcome to the forum.

Swift Handbook downloads.......if you don't have one.

There will be a 20amp in line fuse in the positive wire within 500mm of the +ve battery terminal.
This will be inside the caravan behind the battery box.
