Lux

Sorry, are we talking about the "Lux walthrough" file? It's very simplistic, but it does take you through every step required to complete the game.

I'm not sure which fuse(s) you're missing, so quoting all relevant parts from the file (easiest to find by ctrl f "fuse"):

SECTION III of the station:

-Go south-east, then through the western door to the lumber room. Check the parts on the table and pick up the fuse.

-On the docking module platform, check the note on the wall. Then, examine the filling station.

Examine the control panel. First, open its cover and take the fuse.

-In the lift room, examine the fuse box and place the two fuses (you need to choose them one by one from your inventory).

Once the fuses are placed, program the cart to go down in the lift, then go to the lift and go down yourself.

And later, in SECTION II:

-Time to look for some fuses again. Go to the starting room of section II (south, through the lock, then through the eastern lock, east and through the eastern door). Remove fuses from the lift control panel. Return to the lift to section I (through the western door, west, through the lock, through the northern lock and north). Select a fuse from the inventory and install it in the lift control box; do the

same for the other fuse. Finally, take lift to section I.

Did that help you get unstuck? There's also the possibility of a bug, if the fuses aren't to be found in places listed, but I'd say it's unlikely at this point.
