How does the spark plug work on a Harley Davidson?

The primary receives 12 volts from the motorcycle and allows voltage to build; transferring voltage to the secondary winding where voltage is increased to thousands of volts and released through the spark plug wires to the spark plug.

Can a worn spark plug cause a no start condition?

Which can be difficult for a worn spark plug to ignite. Resulting in hard starting, long cranking, or a no-start condition.

What should the spark plug be on a Dyna?

Just disconnect it from the regulator and test the CPK side of the connector. I checked for a Dyna the primary coil side should only be between 0.3 and 0.5 ohms. I remembered 3 ohms from somewhere, maybe it was my truck. Anyhow if your coil is a sealed unit you will have to test the plug going in it.
