My two cents.
In my experience, there are four terminals on this solenoid. they are: 1}Main battery connection (big nutted terminal). This has two wires on it. One heavy cable from the battery non-ground terminal, and at least one other(usually 10 ga.) going to the Amp meter. (others may be added to this but are not usually correct because they avoid the Amp meter). 2} The "S" terminal (small threaded stud with or without nut). This is the terminal that causes the solenoid to operate. It is not "hot" it is from the start terminal on the key, or start push button. This needs voltage to engage the starter.
The solenoid windings are connected to this terminal on the supply end, and to ground through the solenoid mount on the other end. 3} "I" terminal looks like the "S" terminal (small stud, nut or not). This is a ballast resistor bypass terminal. It is connected to the coil side of the ballast resistor in the ignition circuit. It is connected, on the inside of the solenoid, to the terminal going to the starter. When starting, the battery voltage drops to around 10 volts in cold conditions. To minimize the effects of this reduced voltage this circuit supplies voltage directly to the coil. Helping cold starting in many cases. (this is often ignored and should not be). 4} the Starter terminal (big and with a nut) this goes directly to the starter and causes all actions including engaging the pinion to ring gear. The starter has no other input. This may clarify the operation of the 4 post solenoid. JimN

Memories of a Farmall C - by Monty Bradley. When I was a child, my grandparents lived on a farm owned by a Mr. Walters. The crops raised were cotton and soybeans, with about forty head of mixed breed cattle. Mr. Walters owned two tractors then. A Farmall 300 on gasoline and a Farmall C, that had once belonged to his father-in-law, and had been converted from gasoline to LP Gas. Many times, as a small boy, I would cross the fence behind the house my grandparents lived in and walk down the turn row to where granddaddy would be cultivati
