ALL of my electrical is dead. seems like the battery is unhooked but it isnt. tapped on relay/fuse box next to battery and got some life but as soon as turned the key it all went dark again. I cleaned the connections at the battery and the connection leading from the battery to the relay/fuse box but still dead. not even a spark at the positive terminal from my radio. it acts like it not getting out of the relay/fuse box.

Check for a loose negative ground wire where it's bolted to the body. If that's okay, you'll need a test light or voltmeter to locate the break in the circuit. Start with both probes at the battery, then move one probe at a time to the next place in the circuit until you find where the voltage is lost. Leave the head lights turned on so current is trying to flow. That will insure the problem remains in the circuit so it can be found.
