Possible blown fuse, would like more advice?

Hey all,

I was trying to install some Rough Country lights onto my vehicle listed above, went to hook the lights up and test them, started ratcheting on the positive terminal, struck metal with the ratchet, loud pop, big spark, and now I can’t turn over. Headlights and push button start lights are the only ones that work, everything else is dead. Tried jumping, nothing. Pretty sure it’s the fuse that’s blown, but I would like further advice as to what it could possibly be.
