Southbend A Coil Lead to Heal Connection Point

[T….in Wisconsin]

When installing the coil is it best practice to insert the coil lead in between the heal laminates as shown in picture?

Will it compromise any voltage to the spark plugs if the coil lead is placed on top of the heal laminate and secured in place with the heal screw.

I’ve never seen it done that way.Putting the wire under the screw head is only way I’ve ever seen.The only reason I can see for tucking it between laminates is if the wire was too short to reach screw.

I’m glad to hear that’s the only way you’ve seen it with the lead under the screw.

I’ve have 2 mag plates that have the lead inserted in between the laminates which lead me to believe this was standard practice.  On one the coil was bad and replaced it with a good coil that has a lead long enough to be placed under the laminate screw.  The other has a shorter lead.

I was having thoughts of changing it up and inserting it between the laminates, glad I asked first.

Thanks for the feedback.

The only item is capacitance with wire running close to anything grounded. Every wire has a magnetic (flux field) around it. The more length running close to a grounded surfface, the more loss of energy is lost to ground. I know this from reading about this from reading about neon hi voltage wires from the 15,000 volt transformers to the glass tubes filled with neon or argon gasses. I always kept the hi voltage wires  short & 1.5″ clearance from ground & still had some electrical loss, but acceptable loss.

P.S. A 15,000 volt neon transformer is a great spark plug cleaner at 60 sparks per second.Must be a linear, not digital transformer.
