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?

Hi Altrez,
I am planning to connect the secondary output from my jt to my ignition coil so the 2 screws are connected to the 2 wires of the jt output.

I am not sure anything will happen, however, if the primary and secondary are linked by wires. To me that makes it one wire.
so, that is the part I do not get.

I guess the ohm meter would read the highest when connected across the longest length of wire and less when connected to only part of it. Is that what you are saying xee2?

thanks,

jeanna

OK. I changed the diagram to say ignition coil. I hope that it will make more sense that way.

EDIT: OH! You are referring to the JT coil diagram. It is generic for JT, it was not made for using ignition coil.  I only posted that to explain the dots. Sorry if that confused you.

And a lot of the pins on a flyback from a monitor do not seem to be connected to anything.

@ Gary:

Thank you also for your explanation of the dots.  I have never understood that until just now.  Many have explained it before and it just never sank in until I read your explanation.

Thank you.         (Also thank you to the many others that have tried to explain it before...I just didn't get it.)

I am quoting this post from Yucca over on the Kapandze topic as it may help with the flyback transformer pin ID:

Hope this helps you, it really helped me find the correct pins for my flyback trafo:
