Lets see... what else could I invert?
How to unlock Newton would be proud
Early on in Act II, you will find that the crane has a dead fuse and needs to be replaced. Once you've assembled the three power inverters, go back to the crane and use any of them in the maintenance box to unlock this trophy.
By the time you get back to the crane via natural gameplay, you'll still have one power inverter left, so it's okay if you don't do this right away.
