Cleaned and repaired an International Time Recording Clock. It is a gallery clock that is self winding. I have it on 3 volts, but it is not winding. Measured voltage and there is 3 volts on top part where it connects and I get almost no voltage where it is connected on bottom near coils. Does any one know what voltage is needed for this clock? I have it set up for 2 d cell batteries. Again, it is not winding. I do get a little spark on the upper connector when revolves. Before I put on the pendulum when it did connect the coils that you see attached to box did raise up when the lever on top did touch. Now it is not. Need help getting this to wind. Advice appreciated, thanks!!!!
