1968 Torino GT.  When turning the ignition key to accessory, the radio will not work... Radio works when turning the ignition key to on... I tested the ignition switch and there is continuity to the accessory terminal when activated but no power to the radio when the harness is plugged in.  

Any ideas anyone?

There is accessory power with the ignition key on, so I believe the fusible link is ok.. There is no accessory power with the key turned left to accessory..

Do you have a wiring diagram for your car?  It might come down to tracing the circuit.  Do all other things that receive power on accessory mode get power ok?

Yes.. All other items on the accessory circuit receive power when turning the key to the right, or "on".

I would guess the ignition switch is bad, did it occur all at once or intermittently?

There were some defective factory ignition switches in the late 80's. One example is all the 84-89 Mark VII's should have those replaced. One evidence of those going bad was the two halves of the ignition switch coming apart, a gap showing. That's a critical part of every car, I wouldn't hesitate to replace that at its age.
