For many years continuous duty solenoids resembling Ford starter solenoids...
Did
Not
Exist
1.120-ohm coil solenoids are the original Autolite starter solenoids. The housing is black phenolic. And the (2) #10x32 screws are identified as follows
S for start
I for ignition coil resistor BYPASS
the solenoid mounting bracket was STEEL and served as ground. Without being grounded the solenoid did nothing at all.
The solenoids had a time limit of 30-seconds beyond which it would overheat and char the coil winding.
But the amperage limit was 800
I still use this solenoid for emergency coupling of 2 banks of batteries for starting duty.
For CONSTANT DUTY the tower-type Essex White Westinghouse style solenoid has proven to be more reliable. I prefer the 200-amp model. But there is no question the Ford solenoid is far stronger than even the Essex for high amperage loads. So I am forced to use both. The Ford solenoid has proven to be a winner paralleling battery banks to start 3406 Caterpillar D8R bulldozers.
None of the above is derived from guesswork :)
