I am talking the laminates that go through the coil, after I filed them they looked fused together I used a knife and separated them.

Yeah…that may be problem. Should not have done that. Those layers are insulated from each other and you disturbed that I think. The insulated layers, laminates, are to reduce eddy current losses.

Right. This is what I was getting at, with my previous question / comment.

I’m not sure if shorting the laminations at the edges, or on one end, would have any significant effect. But it’s true that the mfr. did what they could to keep those stacked core layers electrically insulated from one another.

As you correctly point out, they employ this laminated design to reduce the eddy current losses – and any energy lost to eddies is energy that +won’t+ show up in the plug gap.
