Hello everyone. I have a 1983 Chevy k20 with a 350 and I was driving it the other day and it died and would not start back up so I got it towed home and hooked the battery charger up. The battery if fully charged and I checked the wires going out of the battery and they have power. I tested all the wires going into the backside of the fuse box and they have power. So I am trying to figure out what is wrong I have power to nothing no lights radio absolutely nothing. Anyone have any idea what my problem might be. I'm sure I'm forgetting something. Thank you for your time

You started out right by checking power at the fuse box.
However, some circuits in the fuse box have constant power and some have ignition-switched power. If the ignition switch mechanism gets out of adjustment or breaks you might have lost only the ignition-switched power. IIRC there are also at least two fusible links in the power feeds to the fuse box. Do the headlights and marker lights still work?

Ignition module inside the dizzy. DON'T get anything other than a GM module.
How would an ignition module kill all ignition power inside the cab?

Check your fusible links that come off the starter. There are two. As others have said, do you have headlights still? If you have headlights, and both fusible links look good, I'd start looking at the ignition switch

My money is on the ignition switch or at least that circuit

Check the fuel pump? Been there and definitely done that. Make sure its pumping fuel when you hit the ignition.
