Get a new relay and put new terminals on your 30A fuse and your relay. There's enough room in the fuse panel to move the fuse location to other terminal sockets normally. I have to rebuild those small fuse boxes quite often especially in saltwater environments.
Awesome I just put the main 30amp fuse to the batter and looks like the relay is just warm to the touch. Looks like my main battery cable needs to be replaced
