If you go over 59 volts you will blow a fuse and will be forced to reset the breakers. To do this, climb the two electrical towers and flip the switches at the top. The first tower is just to the left of this building as you exit and the second is closer to the Spaceship. You've more than likely already seen both. If you cannot locate them, just follow the wires from the building.
Once you've attained 59 volts, note the gauges on the control panel. One reads the power produced while the other reads the Ships power. If the Spaceship's power gauge shows zero, flip the breaker switches on the towers on your way to the ship. It will be powered when you get there. Go inside.
You've a copy of the keyboard from the book in the library (don't you?). Play the notes in the order shown and enter that same pitch in the control panel on the opposite end of the ship. If you are tone deaf, worry not. You can solve the puzzle by moving the levers to their respective positions by steps. You'll need a steady hand for this and it will more than likely drive you crazy.
