The original 1952 truck has a manually operated starter.
The circuit is basic.

1.)Ground connection (frame/engine to battery negative terminal of the battery)
2.)Battery
3.)Positive side of battery to terminal on manually operated switch (via foot operator linkage).
4.)Output of switch above to (internally) starter motor (starter motor ground is via the engine).

The starter motor should turn regardless of the ignition switch position, headlights, fuel gauge and other electrical components.
Concentrate on making the starter work.

"Adding CFM to a truck will only help at engine speeds you don't want to use."
"I found there was nothing to gain beyond 400 CFM."
