I need something else, but I don't think it's around here. You might need to go to Central Station to beat down a Junker for parts. They're stubborn, but as far as I know they don't feel pain so go wild!
Nice! Actually, while you were gone I discovered that Junkers DO feel pain. Kind of. Whoops! At least they can always rebuild themselves so no harm done!
Anyhoo! Now that I have the parts I can build a detector to track those energy sources!
