Get a new fuse from the warehouse
You'll find Frank next to the building exit #1. You'll learn that an emergency generator is out of gas. Your task is to restore power by replacing a fuse in the generator. You have to leave the building and go to its back (1) #2. Watch out because there is a large group of undead next to the gate.
After a while Willie will open a gate for you so you can continue to the warehouse (2) #1. Get rid of Walkers and Thugs in the area and then break the door. Do not get surprised by a Ram #2 once inside.
Break another door to the small storage, where you can find a fuse #1. When you go back to the warehouse, three Walkers will arise from the floor. Leave the building and go down the stairs #2 to the bottom, until you reach the Block C.
Inside the Block C you'll find a box where you have to put a new fuse in #1 and then activate generators #2. Now it is time to return to Willie in the lab. But you have to be careful because the noise you made attracted infected who will attack you from all directions. After completing the quest you will have an access to the warehouse inside the building.
