Reply To: 1929 Johnson A-45 Spark Plug Wires / Coil

Bucc,
I helped a guy on Johns Old Mercury site using dual fire coils for a single cylinder Mercury. We just grounded one spark plug lead & used the other went to the spark plug. It gave him a much hotter spark, more windings. We used the corona dope for insulating the coil leads. I too have found cracked coils with good electrical values. Covered with very fine fiberglass cloth made for radio controlled aircraft & coated with corona dope. The coil worked well. It was developed for black & white T. V.’s as the scanning beam in the picture tube from arcing to ground in the cathode ray tube. Any time the balance of electrons & newtrons were at an unbalanced condition it would try to arc & balance them. I always have been into “sparky” stuff. The more danger it presented the more I liked it. Built a few bombs for new years too.
