93 Chevy G20 (No Power)

[ynglbc]

One day my van wouldn't start so I bought a new battery and it seem to fix the problem.
Recently I went to start the van and there was no power at all. No lights inside, outside, or panel. Turn the ignition key and still no signs of life. I found a fuse that was blown (illuminator panel). I replaced it but nothing changed. I need to fix this asap since I'm moving out of state. I will see if anyone replies with an idea, if not then I must put it in the shop and fork over the money.

Look to the basics first. The battery may be bad, even though new, something was left on which drained battery, bad connection at either end of the battery cables.
