What I found with mine if you keep folding the coil flat towards the shaft it will eventually break the coil wire internally. Since both are doing the same thing it could be environmental.

In my post I did say the problem was in the coil wire. The coil was replaced and no more problem.

I should of added they replaced the coil for me at no charge, I now never fold the coil flat like I did and all has been well.

I had the same problem, what I discovered was by folding the coil flat to the shaft it put a tight bend on the coil wire, this caused the wire to break internally. If you fold your coil flat you will see this puts a strain on the wire since it runs up the shaft instead of wrapping around the shaft. My numbers would go ballistic as well as sounds but would stop if I bent the coil in a particular way.
