Do not mix up the southern area names
Search results and player posts use South Main Street, south access tunnel, south maintenance tunnel, shelter, and shed. They describe connected parts of the route, not one interchangeable room. Check the active objective text before following a landmark.
Find the door key, then the electrical fuse
A focused Steam help thread points to a key hook in the back of the South Main Street shop. The longer key route places the electrical fuse in a maintenance shed reached after the south maintenance tunnel. Recorded gameplay also shows the electrical fuse being collected during this progression chain.
Use the fuse at the target shed
The demo route notes direct players to a small shed near the second Spinosaurus statue. Use the fuse at the highlighted electrical interaction there. If the objective does not update, verify that you are at the correct shed and that the current build still uses the same route.
