Hi all
does any one know to tell the way to connect
?
KR
It's a step-up transformer, one side will have many more turns than the other.
Get out the ohmmeter, the primary will have less resistance than the secondary.
It actually says what the connections are on the Sparkfun page.
I suspect he wants something else, like how to connect it to an Arduino.

"connect the red and white leads to a 5V source. Be warned, these transformers draw about 3A so your power supply will need to be somewhat robust."
I think that means Red to +5V and White to Ground. Three Amps is WAY more current than the Arduino can provide. You will need a separate 4.8 or 5.0V power supply that can provide at least 3000 mA (3A).
From the Sparkfun page:
Note: Please do not use these to shock people or animals. Seriously, that isn't cool. Actually, be extremely careful with these as they can seriously hurt you. If you don't fully understand high voltage, just live vicariously through the video.
The only thing missing is where it should say "The Mad Scientist should ALWAYS try out his
evil designs on himself FIRST! Then, he'll begin to understand what it is he's trying to do".

I'm not sure where those specs come from. I've got a couple of those and they spark quite happily with a single AA battery. I dread to think what they'll do with 5V3A.

Yes, I know that...I mean I don't know where Sparkfun got them from. They certainly don't need 5V and an Alkaline battery can only put out about 500mA.

Perhaps they got those specifications from the manufacturer who I suspect is SiHON Electronic s Co Ltd:
