No, I tied two leads of flyback transformer together since they are usually made that way. Perhaps this will help.

I do not see how to hook the flyback to the JT? It dose not make sense to me.. Where do you get the connections?

The black  dots  are " Marks "

Take   the wire  you are going to wind  a JT with .
Mark  either  the  end   you plan on  starting  with  or the  end  you planing on ending  with ......... bits  of  tape ........marker  or paint  are all  good ways to mark the ends .
Once   you  have wound    your JT  .......  you simply connect  it  so  your marks match  the black dots  on   the schematic .

Thank you that explains it perfectly!

Xee

I tried  basicly  the exact same  thing  a while back .......only  with a MOT rather than  a flyback transformer .    It choked  the  JT

I am guessing that  the  flyback  transformer  will  do the same thing.
I could  be wrong ....... the flyback  transformer  is quite a bit smaller.

I will  give it  a try  a bit later .
I could  be very helpful  if it  does work

If you look at jeanna diagram you will see there are only 3 connections to ignition coil. For flyback there is usually a lot of pins and there is no standard for which is which. You will need to figure that out for yourself. Ohm meter is best tool.

But every connection is accounted for.. One to the battery. The others to the transistor. Where do you find the connections for the Ignition Coil?
