No gauges, no accelerator, no start

What is your question?

While driving my 2002 Ford F-350 with the 7.3L powerstroke, I suddenly lost my instrument cluster and accelerator pedal. After checking the fuses and repairing the overdrive cancel switch it now will not start and acts like the battery is dead. I have a full charge in both batteries and a full 12 volts to the starter. I've checked all the fuses for continuity and have power across the poles. I even have power to the gauges. I have been visually searching for a short but have found nothing

What makes this problem better or worse?

Everything seems to be getting g worse
