1995 Ford Explorer No power, wont start!

Check the battery? You're not getting any power (no radio, lights, etc)? Does it make a clicking sound when you try to turn the engine over?

I checked, and double checked the connections, everything looks fine. The battery is charged, took it in and had it done. There is power going from the battery to the relay switch, I get a spark when I touch a screwdriver to both connections on it but I still have no lights, no power of anykind getting past the battery and relay switch. There is no clicking or noise of anykind when I try to turn it over. Ive called mechanics, gone to part stores, researched online. Everything. I dont have the chilton and I have to special order it which takes 2 weeks, so I am at a complete loss, no one knows what else it could be. I cant find a break anywhere, but there is no power getting to anything, and I cant for the life of me figure out why. It worked great friday night got it home parked it and satrday morning it wouldnt do anything.

How can I test and repair that? I don't have much elec. Experience.

Thanks, I was hoping I could do it myself since money is tight. Can you tell me what could have possibly caused it?

Thanks I'll see if I can grab one tonight or in the morning. I appreciate it.
