On 7/21/21 I charged the battery for 30-45 minutes, which was enough for the starter. On the drive home (10-15 min), the gauge indicated charging. Earlier today 7/23/21, I checked the battery, and it was @ 6.3V (not running). So for kicks and giggles, I checked it running... It went from 6.3V up to 8V (because it was still charging).

So at this point in time, I guess it's safe to say it's not the starter, or linkage slop. When I replaced the frame to battery cable (years ago), it still had bare metal, so I doubt it's that ground. I haven't replaced the braided frame to starter ground cable yet, but if its kept up like the former, I doubt it's that ground either. I replaced the battery to starter cable (provided that's the one that HAS to be 1 gauge), years ago, and when I did- I applied Dielectric grease to the starter connections.

So if I read correctly, the truck has since started and is now running. You checked the battery voltage and it is now 6.3V (not running) and 8V charging (running).
Just to be on the safe side, I would take the truck or battery to your local parts store and have them check it with their load tester.
If the starting problem happens again, you can eliminate the battery.

8V is a bit too high. You'll end up boiling the cells dry on a long haul drive. The recommended upper limit for a 6V charging system is 7.5 volts, which is adjusted by changing the spring tension on the set of points behind the "F" terminal of the regulator. Lower tension- - - -lower voltage. Always adjust a regulator against a fully-charged battery- - - -overnight on the charger at least before trying any adjustments.

A quick battery test can be done at home. With the ignition switch off, crank the engine for 15 seconds. Check the battery terminal voltage while still cranking. A good 6V battery should not drop below 4.5 volts after 15 seconds of cranking and it should return to 6 volts or more of terminal voltage when the cranking stops.

Buoymaker- Yes, it has since started and ran. And also yes, to the 6.3V and 8V.

Hotrod Lincoln- Will test tomorrow.

Hotrod lincoln- Battery & starter are good, even after 2 tests. Both times, never dropped below 5V. And even after the second test, it dropped from 6.3V to 6V (not cranking).

I have started my 1950 3600 from under the hood. With the key set to on, truck in neutral with the parking brake on, then use a pry bar to depress the button on the starter from under the hood. This will identify if you have slop in the linkage or perhaps the contacts in the starter mounted switch have eroded away enough to require a bit more travel than the worn linkage can provide.
