So you need to interact with each tesla coil, first Tesla coil 1, then 2nd then 3, and adjust them to the number you can see on the big screen.
Once done with Coil 1, go to Point A to jump to Lever A, pull it, now you can go to Coil 2.
Get down to Point B, enter it, now use Lever B, you can get to Coil 3.
When interacting with a Tesla Coil you will see 3 buttons and one lever. With the 3 buttons you need to set the tesla coil to match the frequency on the screen. I don’t think this is randomized, on my both walkthrough i got the same number, so here are the solution based on that:
1. Tesla 1: 250
2. Button 1 – Turn 4 times
3. Button 2 – Turn 0 time
4. Button 3 – Turn 4 times
Tesla 2: 320
Button 1 – Turn 1 time
