Remove the antenna that Dr. Seward said is not working well and replace it with the tuning fork obtained from the Dracula robot.

EDIT: OK, so the old antenna is a star shaped thingie. I waited until I got the "use" icon (hand with a gear) and then clicked on it. The antenna came off and ended up on the workbench over to the right.

1. Place the resistor/u-shaped object on top. Look close on the round object at the center of the resistor and set it to 8 using the +/- icon.


2. Place the electrolysis tube in front of the u-shaped object. Look close at needlelike part of resistor and adjust it to 4 using the +/- icon.


3. Place the ammeter/white square box on the middle left and the rheostat/coiled wires at the bottom. Look close on the coiled wire and adjust the ammeter setting to 7 using the +/- icons.

Once you have done these things, then remove the antenna that Dr. Seward said is not working well and replace it with the tuning fork obtained from the Dracula robot.

NOW you can close the anti-vamp system and take the crank on the right side.

Point and click the antenna on the rats again when the green light light up on the energized apparatus seen on the bottom right of the screen. The rats leave.

Go forward 2x, turn right and go to the main junction of the sewer system.

Look close on the electric panel. Insert the silver ventilation key at the bottom of the panel. A gate being raised is heard. That must be the grill gate to Highgate, we passed earlier.

Look close on the panel again and raise the right lever. The bridge moves to another exit. Turn right, cross bridge and enter.

The empty reservoir is blocking the exit. Turn around and pick up wood planks and place them across the empty reservoir and cross over. Look up and go out the manhole.
