new batteries are not at full charge.....
battery cables do go bad....
battery cables are bolted to things... so rust and corrosion at that point..... even dirt/rust on threads and inserts will stop all that power..

I checked batteries they were both 95%+ and I've got new ends on the batteries no corrosion or loosness there ran two new grounds from the frame to body but idk about the grounds on engine look fine at glance and Idk how to trace the power wire from the relay to the starter to make sure it's not touching or anything gonna try to look at it all when rains gone.. glad to know it's a power supply/ground was worried something more.. also why would the ignition wire have no power could that be related or I was thinking just neutral safety switch on that

neutral switch.. or wires for it.. dirty/failing key switch...
but work in one thing at a time... test .....THEN move onto next issue..
the only battery test I trust.. is the 100 amp load test...

Stop with the starting fluid on the 7.3... Check the glow plug relay and make sure it is working as it should. Make sure all of the glow plugs are working. Pull the fuel filter out and take a look at the fuel in the bowl. If it's been sitting for a long time there is a good chance the fuel is no good.
