    I should also note that one should not let a super magnet get anywhere
    near the armatures magnets. They will slam together, most likely shattering
    the ceramic magnets on the armature.
    They will make a mess of a hair spring as well.
    Super magnets are dangerous to soft human tissue. If your finger
    happens to get between the magnet and a metal piece it wants
    to stick to, it will pinch skin enough to draw blood.

    The latest development is that I have tried filing down the side pillars to effectively raise the position of the pendulum, but this has not made any difference. It is correct that there are 2 colours of wire to the coils so I will test the resistance with an avo-meter. Access to the other electronic components would involve splitting the top case and removing the rear section, but this would also mean releasing the hair spring on the pendulum, which I am reluctant to do.

    Now you know what I meant about not changing anything without knowing what it is there for.
    As for the hairspring, it is only a pin to remove and gently turn the balance until the hairspring is free. Don't lose the pin.

    I strongly recommend that you read back at John Hubby's post. Consider what he mentioned about drag. Look where he mentions a steel pin and a sapphire bearing. See what possibly may be causing drag here. Hairs? Dirt? http://mb.nawcc.org/showthread.php?1...=1#post1097945

    I confess to not having done anything since the last post, as we have had the birth of a new grandchild! Now this has settled down, I may be able to continue. My question is that if I open up the mechanism and expose the electronics, other than testing the integrity of the coils, what else can I do? I only have limited test equipment - an Avo meter.

    We can see if it is a transistor or an IC that runs it. If it is
    a transistor, those can be replaced. The IC is only available from
    damaged clocks.
    If the coil is shot they can be rewound.

    I am in the process of converting a quartz 400 day timepiece to mechanical because the electronics are beyond fixing apart from the hands it will look identical from the front and better from the sides. I offered this route to the customer and he and his wife decided this was what they wanted as it had sentimental value I will post the results if there is interest it will say Quartz on the face which will be a bit odd.
