I want to run the clock and some secondaries. I am getting the clock this week. I just used pictures from the auction. I think I am over my head with this clock but willing to learn. I know nothing about this type of clock, I have a few secondary clocks that I have used a slave driver to run. I have always been fasinated with Master clocks and secondaries. This will be my retirement project!! I will send you pictures of the top of clock when I receive it. I am determined to get it running some day. Can you please recommend a wall wart for me to purchase. Thank you for all your help and will get back to you.Welcome to the forum.
It depends on what you want to do. Just run the clock or run clock and some secondaries.
If you do not have the relay cabinet and just have the wires shown in the photo, you can run the clock with the contacts you have, and probably only need 24 volts DC (or 12 volts if it has 12 volt coils), to pulse the wind coils once a minute. Because you have the two seconds contact, your wiring may be setup to provide 80 pulses per hour, to handle power outages. A small wallwart with at least 150 milliamps @ 24 volts or at least 300 milliamps at 12 volts will be enough to operate the coils. Looks like this movement is wired to provide the pulses. Examine the coils for voltage markings on the coils' linen wrapper, probably in white ink. If unknown start with 12 volts, then move to 24 volts if 12 volts fails to operate the coils. Test coils with the clock not wound full. Do you know anything about basic electronics. Photo of the top of the clock and it's wiring and terminals would also be helpfull. Joe
