Puzzle:Outflow Gate Wiring

In the stormdrain tunnels, the outflow gates leading to abandoned cistern are malfunctioning. Further inspection shows the switchbox connecting different gates to buttons is wired improperly.

Solution
Before attempting to use the switches, the notice next to the switchbox establishes several things.


 * One button can only be hooked up to two gates.
 * Gates 1-3 and Button 2 are broken.

Furthermore, some things aren't explained but are worked out from attempting to solve the puzzle.


 * Blank circuits without switches pass both red and blue currents.
 * Gate 1 is directly wired to Button 1.

Thus, the objective is to wire Gate 4 to Button 1, and Gates 2-3 to Button 2, a task only made difficult by the mangle of cords in the switchbox, and the switches limiting one circuit to another.

This is the correct arrangement of the switches, the first button will become operable.
