When the coil is bound up by pulling it to the trbele side, the coil itself makes the tick. The direction the coil is wound changes the  side of course. I wonder if lubing the coil would work? Anyway, the factories may be using a wire that causes this<o:p></o:p></p> </div> <div> <p class=MsoNormal>Thank you so much Zeno.
