Sudden powere loss at ignition sw.

I have a 1975 F250 Ranger XLT and today the power to the ignition, lights and fuse panel disappeared. There is 12V at all 4 terminals of the start solenoid when the key is on and to the regulator. Fusible links under the hood are all ok. HELP!

My first guess would be fusible link, but you checked that. Is it a camper special? More fusible links to look at in that case. Does it crank but not fire? Is the ignition switch ok or worn and floppy?

The ignition sw is fine. It is a camper spl. It is completely dead. No power to the fuse blocks or to lights or to the ignition sw. Disappearing somewhere between the input post on the starting solenoid and the ignition sw. I have ordered a new starter solenoid since this one has no reading on the coil.
