Good morning guys.

I trust you all are well?

Please can someone tell me where can I find the fusebox diagrams on the net? I didn't get the diagrams with the car and no manual, its second hand and not even the battery cover is present anymore, I am having some major problems with the fuse box by the battery, and after cleaning it taking it apart completely, I suspect that I have to replace some relays. Start of problem, the damn thing got wet probably because the previous owner drove through water and not having the cover on, and I found some traces of a rodent making it its home (toilet ). Please help me. My car won't start, and I am getting a lot of faults and errors on the dash, and from what I have read, the fault originates from that Fuse box.

Howzitt.
Here is the manual

Thank you very much!

fuse board by the battery can be taken apart to check for moisture damage and shorts in the fuse board circuit caused by water, as quite common problem if there is no fuse board battery cover fitted, it may be fixable if not burnt too badly and you can clean up any shorts or bad connections, should it be your related to your faults...link below to some info from the guides section.

Though having read through the forum it would seem from other thread you have that you have already given the fuse board a look at and checked the above,
