I believe that the purpose of the starter contactor in Bob Nuckol's drawings is to isolate the starter cable from the battery.
If the starter cable were connected directly to the battery and it shorted to ground there would be no way to disconnect it.

Subject: [FlyRotary] Starter solenoid
What's the steady-state current draw of the starter
solenoid?
Why, in all of Bob Nuckol's wiring diagrams, is there
a starter
contactor switching the heavy current to the starter? There is already
a contactor in the solenoid. What am I missing here?
