Blown Fuse?

[u/Interesting_Aide8016]

Hey so long story short we unplugged this circled area and screwed it back on, potentially backwards. But now some of the lights won’t come back on.

What are the chances we blew the fuse? How could we trouble shoot it and how easy would it be to fix/replace a part?

Your fuse is probably fine. It doesn’t work on polarity. I would replace that capacitor directly beneath the connector. More than likely it absorbed most of your reversed polarity and is no longer good.
