Unfortunately, my cow worked a bit. Another Wackelfigur next door went on the windowsill from as Schmitz cat ... the cow jumped only slightly with his head!
So pry the bottom plate and looking at the inner workings!
Here a digression about how ... the solar cells give their energy to an electronic part, which in turn pass on the power to a small wire coil, which is located on the bottom of the plate. Current in wire winding = magnetic field! The electronic part between the current flow stops, or reverses direction (leg I no electronics) - thus the magnetic field is reduced again, or vice versa, even in the polarity!
At the cow a pendulum depends on which a magnet is fixed (in the cow are there a total of three pieces (left / bottom / right).
The magnetic field of the coil so attracts the pendulum to or pushes it off and the musculoskeletal system of the cow comes running into.
In my cow, which has virtually not moved, the lower magnet was (poorly attached with glue) loose and hung on one of the other magnets. The delicate balance of power was thus naturally no longer apply.
(He has held there without glue only on the basis of magnetic forces) I loose magnets simply to his correct position set breathed and thus the cow back to life - now it wobbles as quickly as your other Wackelfigur window.
I hope this helps one or the other its "defective" to repair cow: O)
Because of this small error should be "cheap products" do not occur even when, but is nevertheless easy to repair, there is of me 4 stars.
The cattle is just awesome!
