Hi can anyone tell me if a ldv400 has a single main fuse, ?

I have a k reg ldv400that was running fine, i stoped and tried to restart but have lost all dash warning lights and she wont go as i guess the fuel isolator is not working either. The engine turns over freely so i am thinking a fuse has gone somewhere, they all seem ok in the middle of the dash so is there another fuse somewhere. Thanks
