In a CDI System, the ignition switch wire, just "arms" the CDI box. After that, the "box" takes Battery voltage from it's own input, steps it up to something like 525 volts, modifies it, and presents it ready to plow into the coil, at the behest of the signal generator inside the Distributor. Until that moment the coil has not seen any voltage.
Therefore, with the key on and engine not running, there should not be any voltage going thru the coil. In this case, the coil is just a transformer, stepping the 525v up to 30/40 K-volts; but it has to be lightning fast, especially during multi-strike operation.
By about 3000 rpm, the coil can't do it anymore, and so the brain-box switches automatically to Single-Fire.

IIRC , in Single-Fire mode, the output amperage is increased, so now you are on a par, or nearly so, with an HO Induction Ignition System.

On a Mopar, you usually have to run the "crank" and "run" wires from the ignition switch together, to arm the box. However this feeds back into the starter during "run" mode, in Park/Neutral, sometimes with enough voltage to cause the starter to want to engage. To prevent that, I ran the brain box signal wire thru a relay in crank mode to isolate those circuits. Actually IIRC, I ran both circuits thru relays, so that my 1968 ignition switch doesn't have to handle the current.
However you do it, the box needs power in BOTH "crank" and "run", and the factory starter relay, signal-side, should be dead in "run".
I don't run an electric choke..... no choke at all. If I did, it too would be on a relay.
