Voltage drop

Exploration Stage: Amusement Park
From: Carlos Light
Description: It is a magnificent machine, but all of them are broken at every turn! We need to fix it before the city goes out of control. First, we need to reduce the voltage with a portable power cutoff device. But where did I put it... can you help me find it?
Completed: Thank you for finding the power shutoff device. This will temporarily interrupt the flow of electricity and allow you to safely repair the machine. Let's hurry up and get this done before the effect wears off.
