I can't imagine why there would be contacts that short out the coil circuit. You will need to figure out the timing of the activation of the contacts to determine their possible use.It measures 3.0 and when I engage the points at the head of the coils the meter stops beeping and goes to zero to show no resistance.
If it does short the coil, there would need to be an external current limiterI'm not following how shorting across the coil could extend the time the coil holds the armature. But it would prevent back EMF problems.
Having the coil shorted when the pulse comes to draw in the armature would prevent it from working at all, and also short out the source of the pulse, unless there is also a series resistor somewhere.
It won't run on straight DC
For the sake of useless argument, we will refrain from referring to this this movement as a master clock until we have fully established the uses of the two sets of points actuated by a cam on the back of the movement. On the other hand we have establish
IT WILL AND DOSE RUN ACTURATLY ON STRAIGHT DC You talk of switches and what you say is the way the movement should be set up to run. I ask with all due respect. Have you ever seen another movement solenoid driven like this? And by any other make in the past and if so who , where and when because it would be a great help in answering a lot of questions.
If there is any other actions of any kind that where to take place in the operating of the movement it has been established that know matter what they might be or do they can in NOWAY change the fact that the armature must be
activated between 400 to 500 times per minute to move the minute hand one minute.
After running the movement 16 hours we are 4 1/2 minute slow. However we are dealing with all the things associated with getting a movement back in smooth running condition therefore actuate time keeping by the movement can not be expected at this time or stage. We feel that the movement needs more resistance to run first on a higher voltage therefore running more actuate. resistance is now being applied. Update to come in a few days.
I appreciated any an all comments and or suggestions on the subject for in the search of the true on just how this movement operated Disproving possible actions is just as important as proving possible actions.
Having a great time with this thing!!!!! More Videos coming stay tuned
