That will probably be the easiest.
Turn off the CB in the main panel feeding the panel.
Label each wire for where it connects to the line and load screws. Then disconnect them all.
Then disconnect the wires.
Move the good relay into that space and then reconnect the wires.
The relay was the issue, thanks for the assistance. I'd buy you all a beer if I could but you will have to settle for a few pool pics...
Thanks to @1poolman1 as well!
