No Crank, No Lights, No Click, Battery Not Dead?

Thanks for all the replies. Strange thing...a day or so ago when I left it "dead" in the driveway after I headed off to work, I came back that next morning and opened the door. Dome light did come on, and she started without any problems. Well that's awfully weird, I didn't touch a darned thing! Nonetheless I went through the diagram starting at the battery. Wiggled connections, made sure everything was nice and tight. Got to the fusible link and it's connection to the ammeter red wire. Began to fiddle with that, pushing it together and twisting it. Heard a very tiny 'click' when I did that. They feel pretty tight together. Crawled under the dash this time to try and look for any other problems. I'm surprised to see my under dash very clean, with no corrosion at all and from what I could tell, no loose connections. This past day or so I've been driving it around for errands, drove it to work, and after overnight sitting everything came back on. I'm thinking it was that little 'click' from the ammeter to the fusible link that got a better connection. Will be driving it again tonight for work (I work closing shift) and I'm thinking I should be alright. If not, well....you'll hear from me again lol!
