Keep moving through the blue-lit corridor to its end. You'll emerge inside a small room. Rotate your viewpoint around the room and discover some sort of diagram. The diagram contains icons and dotted lines moving between each icon. This represents Voltaic's power and its flow. Since none of the icons are currently lit, Voltaic lacks power. Once you get the power up and running, the icons (or the locations they represent) will glow signifying power.
 This diagram reveals which Voltaic structures are receiving power. |
Locate the ladder inside the room (across from the diagram). Ascend the ladder to the top. You'll be on a small platform overlooking what appears to be a form of hydroelectric power. Saavedro has done some sabotaging here; not all of the controls are functional. From this position you can see a waterwheel and a huge damlike door. To start the hydroelectric power, the waterwheel needs water--time to move the dam!
Turn the red wheel to open the large wooden door. This lets water flow against the waterwheel. Descend the ladder back into the room with the power diagram. Face the unexplored tunnel (across from the entrance) and proceed through. You're back outside, and a locked door blocks your path (still doesn't have the necessary power). Ignore the door and turn right. You'll spot a ladder descending beneath the waterwheel. This ladder is inaccessible unless you have adjusted the position of the dam.
 Closing the dam opens a new entrance below the waterwheel. |
Proceed down the ladder. When you reach the bottom, press the red button to open the door. Once inside, examine the mechanism in front of you. You need to connect this gear with the waterwheel before it will spin and create the necessary power. Use the crank on the left to raise the mechanism. Return up the ladder and retrace your steps back through the tunnel.
Explore the tunnel connecting the diagram room with the ladder leading to the mechanism you just moved.
Despite your efforts, the water still isn't hitting the waterwheel--thus, the waterwheel isn't spinning and generating power.
 Here's a tricky part to starting the power: Make sure you look through the damaged wall and touch part of the waterwheel. |
Face the diagram room and explore the right side of the tunnel. Look just before the diagram room to spot a damaged wall segment. Click on the damaged wall to see a part of the waterwheel. It's the part of the waterwheel that catches the water!
Click on the part of the waterwheel visible through the damaged wall. If you have completed all other tasks, the water hits the waterwheel and begins to spin. This generates power! Return to the diagram room and look at the power diagram. You'll notice that two of the icons are lit. The diagram on the left represents the waterwheel, which you just powered; the diagram on the right represents the door at the end of the tunnel (notice the straight dotted line connecting the two).
