Kieninger&Obergfell Electro-magnetic clock

[jjccamis]

I'll try to be brief. I have the above named clock, magnet through a coil of wire. Cleaning the battery compartment terminals and installing a new battery yielded no positive results. There is a circuit board beside the battery compartment. I realize there are only so many components that can fail. What is the most likely point of failure? If it is the coil, can a replacement coil be obtained and where would I have luck finding one? Can any of you suggest any other troubleshooting measures I might try? The mechanics seem to function properly while the pendulum is swinging before stopping.

A picture of your clock will help.

Your post might be better suited for the Electric Horology portion of this board. Maybe a moderator will forward it.

If yours is the style clock I think it is, the response will likely be to find a replacement clock.

Best,

Dick

Here is a pic of the clock in question. You'll have to rotate it. Hope this helps in some small way.

The parts on the circuit board are usually not the
issue, it is usually the coil. The older ones use
germanium transistor that would often fail but
these use silicon transistor. Sometimes the electrolytic
capacitors can fail but I'm afraid it is most likely
the coil. There is no replacement other than to wind
another.
I have a failed on as well but I need to figure how
to get it out of the case. I've not tried that yet.
Anyway, you can check the coil with an ohm meter.
Lift one lead and measure it. I don't know what it should
be but I suspect 1K to 2K someplace.
Mine has the germanium transistor built in the coil
so it could be anything.

My running one is just like that. It is working fine. It is the
oval one that is sick. I've been known to fix these kinds of things
but I need to figure how to open the coil. I'm thinking
heat might do it.

This might do better in the electric clock forum. I'll move it over there to see what they can contribute to the conversation. There will be a redirect here for a month too
