I have a clock that I want to mount in a wood case and run it with a battery. It has a magnetically operated lever which has springs and a racheting gear. When the lever runs reaches the top and runs out of tension, a set of points close to operate the magnetic coil and draw down the lever. I tried using a regular 9 volt battery to operate the coil but it moves the lever only slightly. What would I need to do to get the clock to run on batteries or maybe a plug in ac/dc transformer? Thank for any information that you can provide.
