07 A8L...after water leaks, I'm getting several errors related to Circuit 30 low voltage. After checking fuses on both side of the dash panel, found plenty of corrosion (white dust residue) all over the fuse boxes and fuses. I cleaned out all of the fuses, but the back of the fuse box has corrosion on it also (the wire and terminals). When I removed the fuse holder, I was not able to clean out anything because I couldn't figure out how the main supply (large diameter wire) was connected to the terminals.

I want to remove the main supply wire and clean corrosion and make sure I have a good connection. Any help will be appreciated.
