Well I did a video that shows it running and running and running. Note that I first point at a small gear that drives some other gears never moves I know it must be how it stops the chiming and striking.
Hmm. Most of these have a mechanical method of using the traditional rack lifter to make the electrical contact which starts the motor running. This seems to make those connections electrically. The motor that runs the chime/strike should turn on and off. This should also work in unision as to where the hands are. The wheels you pointed out in your video that don't turn while the strike is running are the wheels that set the hands. So if you use the hand setting knob to turn the hands, does it start stop the chime/strike?
I'm inexperienced with this movement as it must have been short lived in the design period of such transitions from mechanical to electrical clock movements. The rotational switching method is similar to a variable resistor pot. I can see why it wasn't around for long in the scheme of things. Such movements would have been replaced the first time they played up.
