Battery has full charge, but everything is completely dead . The only thing that lights up is tha A/C indicator light when you push the button.

What is your question?

Absolutely no headlights, emergency flashers, ignition, radio, dash lights, . Absolutely Completely dead except for the single LED indicator light on the A/C button
