Ford Focus MK2 main fuse?

Hi, I have a ford focus MK2 and I think the main fuse might have blown. I have checked all the fuses I can see in the engine fusebox but I'm just unable to confirm which fuse is the main fuse. The website below shows a diagram with labels for the fuses.

If anyone can help out then thank you.

The first thing you need to do is stop "thinking" and start "testing". A test light is just a couple of bucks and it will last for years to come.

The main fuse is on your positive battery lead at the battery. If you have power beyond the battery the fuse is not blown.
