I got two new coils on Ebay. They have two circular solder points in the center on the side of the coil. I assume these are for the secondary and should be connected to the spark plug wire? Is this correct? Do you have instructions, diagram or pix you could send?


The coils with "two circular solder points" are for motors where 2 cylinders
fire at the same time. For the Mercury's that has the magneto that uses this
style coil you need the coil with a single connection. They are available but
cost several times more.

Do these help? I cut the insulation back a ways to allow the wire to slip under the coil without hitting the stator plate. I then slid the entire coil inside a stub of bicycle inner tube material to insulate it. Coil throws a good spark!

Not nearly as hard as a KF5, bottom seal aim the seal lips DOWN & replace the top too. Ground one of the hi volt lugs for super fire,

I'm surprised that the inner-tube rubber is adequate to prevent arcing to the mag-plate. Interesting job.
