    Kundo.JPG The clock I bought will look like this when I am finished. My clock has a battery block with 4- 1.5v batteries. I am a newbee and need help the clock does not run, where do I start? Is there any service manual to be had? If not where do I start?

    There is no book on these. The movement should not be oiled.
    Does yours have a good suspension spring?
    If so, does it continue to run with a battery in it.
    The 4 cells go in parallel to each other. To make it run
    for experimenting and tuning, a single AA cell will make it
    run for several months. If you decide to load it with 4 cells,
    it won't run any better, just longer. Always replace the
    4 cells as a brand new set. If one cell is run down when
    replaced, that cell will leak and damage things.
    Which reminds me to ask, has there been a leaky cell
    in the holder that has caused corrosion?
    If so, you must remove all the corrosion and neutralize
    the base caustic stuff that came from the batteries. To do this,
    I recommend soaking the battery holder in white vinegar
    for a couple hours then rinse.
    The contacts must be clean. Rubbed with a small piece of
    600 sand paper is often needed to remove any corrosion.
    If the clock runs, you are in luck. If not, it indicates the coil
    assembly has failed.
    Of course, these are no longer made and your only choice
    is to either get a donor or attempt repair of the one you
    have.
    We can talk about that later when you know what you have.

    Kundo Mov't4.jpg Kundo Mov't2.jpg Kundo Mov't.jpg Kundo Mov't3.jpg Thank you very much for the reply. I must say again, I am a newbee that wants very to learn. Please be very specific with you replies. The springs that hold the batteries are very rusty so I am going to give them a white vinegar bath. What is next?

    Vinegar, will only neutralize any battery acid, that may have leaked from bad batteries. After the soak, clean all of the battery contacts with sand paper, as Tinker stated. (Make sure to remove any or all grit, or dirt left behind.
    Check to make sure, that the suspension spring, is in good shape. This, will be suspending the pendulum, from the movement. A lot of times, these may split, along the top or bottom block. (Handle this part with, care...)
    If the spring is in good shape, install four fresh batteries, and set the pendulum, in motion. Just give it a gentle push.
    Make sure, that the rod, that arcs through the winding barrel, isn't touching the barrel. Also, that the base of the clock is level.
    If everything is correct, the clock will/should continue to run. If not, you may need to look for a donor clock.
    Keep us posted.

    It looks like the shipping pedulum lock is holding
    the pendulum in the pictures.
    There is a thumb screw on the back, about a third
    the way up. You need to unscrew it. Hold the
    pendulum while unscrewing so it doesn't just drop.
    once the screw releases, let the pendulum down.
    If the contacts are clean and the clocks electronics
    are working, it should mantain a swing.

    Hi,

    I agree with Tinker the pendulum looks like it's locked. If a clean up and new batteries won't get it to run the repair will be difficult because the electronics are contained inside the coil and are difficult to get at.

    my experiance with these is:first check all contacts (battery to battery-box,battery box to wires,wire to clock frame resp. solenoid etc.)The pendulum must swing freely through the solenoid without touching it,if not , Your suspension spring-the flatt double spring the pendulum is hooked to-is damaged.I don't think the pendulum is still blocked by the transportation skrew.The little induction magnet should be there,it's behind a polished steel cap at the right end of the circular steel bar forming the bob of the pendulum(looking from front).It holds magneticaly,lift up the cover and see if it's there,don't remove it .If Your clock doesn't want to run now You have a problem.These clocks came in two types,one with a switch board in the base of the clock,behind the battery compartment.This type is most probably intact.The second type has all the electronics incl. a Germanium transistor integrated into the solenoid,and-sorry to say-these Germanium transistors often are shot and not replacable- at least not with reasonable amount of effort and money.If they run,they are beautifull.Hope You get Your's running.
    Best

    I was wondering I have the same clock but is running slow is there a way to speed up or slow down this clock.

    Have tried raising the bob on the pendulum? You should be able to rotate it to raise it.

    Thank you very much I did not see the arrows on the bob feel kinda of foolish but now I see them. Thanks again.
