As to avoid to spoil to much I'll not tell something about the story behind this quest. So when you want to know what happened, you've to collect all 7 notes from Eliza which can be found on 12 possible locations on her trail. But to unlock the shed and find the treasure you've to repair and activate 3 generators too.

After you quicktravel to the Cranberry Island Bog you'll notice a broken house on the right with some containers under it. A door inside one of the cargo container will lead into a bunker. But to open it, you've to repair and activate three power generators on the island.

Standing in front of the bunkers's entrance just turn to the south and you'll see the genarator #1. To repair the electric you need 6 copper or 5 Intelligence to fix it. Or just try to "kick it".

Note: Don't forget to activate the circuit breaker before you leave.

Next to it, on the concret you'll find also Eliza's Map of Home which leads you on the trial. The generators are marked with a flash.

To find the other generators just look up and follow the cables. Going to the northeast you'll find #2, following the cables to the west you'll find #3.

Now you've to reroute the electric again. Either you can fix 4 circurities, alble to shorting it out (level 6 preciption) or youv'e the chance to "Jam some Metal in it". The box is behind the 4 towers in the background.

Note: Don't forget to activate the circuit breaker before you leave.

This time you've have to repair a broken tube, next to the generator. Either you use 5 steel or
or you're strong enough (strengh level 7) to bend the tube. You can also get the risk to "try to bang on it"

Note: Don't forget to activate the circuit breaker before you leave.

After activating all 3 generators you've to return to the bunker entrance. When you did everything right the 3 lights aorund the door should glow. But be aware: opening the door will set 4 ghouls free which are attacking you directly. After taking them down, you'll find the key to the Cranberry Island Supply Shed in the footlocker next to the entrance.

After getting the key go to the Cranberry Island Supply Shed where you'll find tons of crafting supplies inside.
