Gary:
I wasn't paying too much attention just before to who was posting, I was thinking about the 2nd coil and using another one in reverse fashion and assumed it was Jesus who asken me.

Sorry about the mix up.

Hope Jesus can fix his monitor, I have to be on my way to town shortly or I won't have any dinner to eat tonight.

Lots of confusion here today

I was talking about the yellow schematic Jesus posted .

It looks like you had the same idea I did.........but for a different circuit

Today  I learned the hard way not to trust everything you buy on ebay.  I had a few very nice working boards from the fuji, each with a different configuration.  I was so proud of them.  Then two of them stopped working.  I was disgusted after all that work.  So I took those two apart literally destroying them, but I figured, why not since they had quit on me.  THEN I DISCOVERED THE TRUTH.  Those darn alligator clips I bought on ebay were not working.  I had the thought to test them for continuity, and sure enough, it was the alligators, not the boards, that were at fault.  Erghhh.....

Now another thing.  I told you before I got the neon working, and then I found out it was an led.  Well, when I was playing around with the boards, I got the LED so red, I thought it might burn up.  Then I took a neon...a much larger neon than normal, and IT lit up.  However, at the same time, the cfl bulb would not light up.  So, why would a NEON work, and not a bulb?  (cfl)  The bulb does work....I have been using it all day....and it still works.  By the way, only one side of the neon lit.  Someone said why that was, I think, but I don't know where to look for that post.  So, why would the neon light up only on one side?  And it was a very bright light, too.
And the purpose of the neon was what?  To keep the high power from blowing stuff?
At least I have not had any shocks yet...knock on wood.

Neon lit on one side means DC, AC will light both sides.

Thank you Gary
if I can find this product in Oz it will save me some time, which means more time playing with JT's.
