That's the simple answer, but that fuse block needs some attention.

At a minimum, I'd clean the snot out of it and inspect all the ends that are terminated there. Next level of service would be to replace the fuse block, which would be a pain, but not that expensive with a bladed style block.

Truth be told, you could probably go many years with just some cleaning, but that block does look pretty ratty.
