Feedback To Source

I am very glad to see you are not giving up.  Hey, if this were easy, everyone would have done it by now.  Don't ever give up!

I just had a wild thought.  You said that you had a loose connection.  On another topic i think you posted that a loose connection has a very high resistance, so, why not place various resistors of increasing value at that connection to see if you can duplicate the effect of the bad connection and see if it works again.  This time, you would be able to control it.  Just a thought, I may be way off here.

thank you @pirate !

That is the idea I have too. But instead of various resistors I will use a 20k pot or a 50k pot that I have. I bought a multiturn trimmer and it does not trim anything, you can be all day turning it and there will be no change at all.

The trick that must be found here is which leg to put the pot on or is it that both legs must be trimmed.
By the legs I refer to the base and collector legs, the right self charging setup lies between this two coil legs.

I will play a little with the self charger to see if I can make it work again.
It should turn the light on when the switch is open and turn the light off when the switch is close.
If for some reason I cannot make it work even after rewounding the toroid coil and building it back step by step as @resonanceman recommended at the "jule thief" topic.

Then I will use the new circuit and see if it works.

There is a circuit I posted before that was called:
YES Gate / NOT Gate.

I was trying to wind a new toroid and start again step by step.
Looking for a toroid winding information I stumbled with this circuit again. It is not the one I made as plan B.
Because of the supposed double signal it has I tried it as a test for the switching I needed to accomplish the battery swapper that I am still working on it.

I tested it with the old self charger toroid and the thing began to charge very slowly.

I put a pot as a resistor and the pot did not worked as expected.

I tried a 100k and the self charger charged a litle more very slowly.

I increased the resistance to a 1M resistor with colors black, brown and green and it is charging as it was when the connection was loose.

So the changes were:
Adding a red led between the emitter and ground and a 1M resistor from the coil to the transistor base.

Does anybody want to verify this?

Testing and retesting the self charger circuit, I found that its work can be disrupted by anything.

Also the quantity of charge produced is so small that I have not been able to find a good use to it.

I will try to get something better that can be used as a feedback to the source.

As for example the battery switcher commutator.
