@ jeanna

I get 1.3 VAC across those secondary leads with the array unconnected.

That is strange. I would expect that there would be at least 10 VAC there. I do not have a circuit built now. but I did this a few years ago and I think I was getting about 20 VAC. Thanks for checking. I am not sure what is going on, so I guess the best thing to do is just keep experimenting.

@ MK1:

Jim has a scope, perhaps that would show what you mean?  If you could "see" it, then you could adjust and fine tune it.  I don't know if a scope would show this or not.....

So what is your view on what is happening , i don' have much more than a digital multimeter.I can't really see more than this.

But i was thinking that if one could calculate the speed a witch the coil collapses when switch of and tune the device to go back on before the collapses finish the energy is recycled before exiting ? But that's is only theory .

i really am not sure, it still puzzles me. i was stupid and took it apart. a couple months ago, heairbear was over and we were talking about step charging a coil, so i rebuilt it and showed it to him. i still have the coil i used, if you want i can rebuild it again and post you some pictures.

Sounds reasonable to me.

That could work just as well with the jt , That is if plausible.
