Fallout – Why does the Castle settlement show insufficient power

fallout-4

My settlement at the Castle has 32 power for three people and it's still showing up as red. What gives? Is there some hidden object that I need to power in order to satisfy the Workshop? Because I found the one existing pylon in the courtyard and connecting it didn't solve it. Or is this a bug?

Best Answer

There are a bunch of lightbulbs and an industrial water purifier that need power.

You can see the purifier out of one of the windows. There is a pylon with a switch on it in the courtyard you can connect to to hook up all the light bulbs and the purifier. It was not obvious to me until I traced the wires from the lights.

Since there's a switch on the pylon, you might need to make sure that it is actually switched on.
