Thanks for any help.
There's a breaker box that you have to turn ON first. By one of the doors, I think; it's been a while.
I believe the fuse box is near the workbench. Put up a light near the workbench and turn on the fuse box and see if that light comes on. If it does, then the electricity is working. Then to get it working in the rest of the house, add more of those pylon thingees like the ones that are already on the walls and connect them with wires so that everything runs back to the fuse box.
