Water Leak - Storage compartment

We have 2010 FourWinds Chateau 29BG with the 3 slides. On the driver's side exterior there is an outside storage compartment under the slide. After a rain or washing, and the slide is closed, there is water leaking into this fiberglass compartment. This compartment is next to the generator compartment. In the storage compartment, there is a wire loom coming down from the top of the compartment and goes to a box which goes into the generator. The water is seen leaking down the wire loom. It appears the source of the leak is above the wire loom.



I ran water on the roof for awhile and didn't notice any leaking down through the loom but when I sprayed water along the slide, below the window area, I noticed water dripping from the loom. I have removed the existing weathered sealant at the bottom of the slide where the horizontal slide molding is and replaced it with new sealant. After last nights rain, I still have a water leak although not as much as before.



Any thoughts would be appreciated.
