One thing for all to keep in mind and that few seem to know who do not have a electronics background is that you should never crank over a a motor with a main / central spark coil for more then 5 seconds with no place for the spark to go, as in no plugs hooked up, or the cap off but everything else hooked up.
When the coil is still being triggered the coils secondary side is still producing a spark and with no way to get that high voltage produced to ground the coils secondary winding will arc across itself.
The higher the secondary voltage the coil is designed to produce the more likely it will be for that voltage to arc thru the enamel insulation used on the wire of the secondary.
On a factory 45 year old spark coil the insulation on the coils secondary windings is likely already compromised and ready to fail just due to vibrations and heat cycles, so don’t push it over the edge!
