If you have no way to check for HV than the spark gap, then also note that frequency of your driving circuit is not too high. It was impossible for me to get sparks above 1-2 kHz switching frequency.

A good point, as xeno says don't start at too high a frequency, bring it up from like 100Hz and tune for widest arcover.

Make sure you have your pins mapped correctly first. If you hand pulse your primary with leads on a 9V battery then your secondary should produce sparks over a 1mm gap no problem. That's a good way to finally verify pinouts.

Your modern flyback will almost certainly contain a HV stack diode on the secondary output, so you wont get AC out, it's a good thing in these circuits though because if you want to charge a cap you can just hook the cap straight to the output and you won't need an external diode.

If you charge up HV caps any larger than your thumb using this then please my friend be very careful, keep one hand in the pocket when taking measurements or reconfiguring leads etc.

One thing I have never tried but I may do soon is this:

A flyback trafo has many different winds because it is also used for stepping down for filament heating purposes etc. So I think maybe a Joule thief type oscillator could be made by using the lowest ohm winding as a trigger coil, you would have to put a resistance before the transistor base. The good thing about this is that the trafo would probably run at natural resonance with such a setup.

Jesus,
how did you attach the spark gap?
I assume you drive the flyback with a sine waveform?

EDIT: If you have no way to check for HV than the spark gap, then also note that frequency of your driving circuit is not too high. It was impossible for me to get sparks above 1-2 kHz switching frequency.

I did not attached a spark gap yet.
I am trying to drive the flyback with a joule thief circuit and a three pack battery.
I have not anything to measure frequency. Believe it or not I am a newbie.

@Jesus,

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

Thank you @yucca !
I saved the whole thing on my hard disk, because on other links that pointed to that document, the link did not work.

Lets see what I can do with all the information that I have stored.

@mrvideo and @all

I did the 2b-10c test and no spark either. I think that the monitor was thrown away because it has the flyback damaged.

@all

I changed the transistor to a 3055 NPN and used a power supply at 9v
also connected instead of just touch, the pin #8 to a wire that was attached to the HV pkug with an alligator, leaving about 1/4" of gap.

And the flyback began a buzzing sound and I did it!!!!!!

It lasted about 10 seconds thoug, the power supply quit on me.
Another loss, but I did it.

So what is it that you expect to be sparking here then ?

The circuit probably died because you have not used protection diodes on the JT transistors.
I have killed 2 MOSFETs and 6 555s before i had the circuit protected enough and i only used a harmless ignition coil. That flyback can havoc much more man.
Put a Diode also inbetween PLUS of the power supply and the postive rail of your circuit !
Some HF inductive throttles would be good too there, but if you don´t like your neighbours then nevermind 
But good to see that you got it going. Keep it up !

Thank you @xenomorphlab ! and thank you to anybody that has helped me on becoming an electronics man.

By the way what is an HF inductive throtle?
