Engine run on need help fast!

Hey everyone I have a run on issue that just started to happen. I built a71 c20 from ground up. Since I've been driving the truck I've had no issues. It's the original wire harness (with a few mods and additions).

It's a 3 wire interal regulated alt and the signal wire has a diode in it to prevent run on. And it has been working that way with no issues at all. This just started to happen this morning. Could the diode be bad or is the fault in my ignition switch?

The way I have it wired is from the starter solenoid to the battery post on the alt then from the regulator to the battery post on the alt. The other wire from the regulator to and ignition hot on the fuse box (the diode is in this wire).

The way I'm turning the truck off is disconnecting the wire going to the fuse box.

This is my MAIN driving vehicle the whole family uses this truck so I need to fix it ASAP! All help is welcome thank you
