It sounds like there is an issue with the battery charge wire circuit that connects to the fuse block under the hood of your 2009 Chevy Silverado. I attached a link below to a page that shows how these connections are made.

It is also possible that the fuse is blown on this circuit too, you should check your vehicle owners manual to determine which fuses pertain to the 7-way at the rear of your vehicle.
