I know just enough about electrical stuff to be dangerous, but doesn’t the current draw on a device like an automotive starter depend upon how difficult it is for the starter to turn the motor over.
For example, the same starter on a 7.5:1 compression motor will draw fewer amps than that exact same starter on a 11.5:1 compression motor.
And isn’t also true that the current draw in either case listed above will not be a stable flat line. The initial current draw just to get the starter motor to begin to turn the engine over will be much higher than the current draw to keep the motor spinning.
