[FROB182]

Spoiler below!

Push the box off the cliff in the generator room, it contains the battery, pick up the battery an put it in the generator (left side of the wheel with the I above it) then turn the wheels in the correct order (provided in a note) go up to the generator, pull the lever, fuse will blow then you can replace the fuse and try again and it will work, as for the radio it has morse code. The note to decipher that is in the closet where you found the fuse. Was you have that use that code to open the door at the gate.
