The coil shown in diagram is secondary of toroidal transformer

At the secondary of my coil high voltage comes and make spark without LV circuit in series.
This HV have some properties, It will not spark when 10KOhm resistance is in series with the coil. But it works if the resistance is in parallel.

Ignition coil with resistance in series generates spark, But if 10KOhm resistance is in parallel with Ignition coil no spark at the spark plug.

In above test I have not used LV.

with gasoline, carbon deposition on the tip of spark plug creates problem with coil based plasma circuit.

It is now the situation OUTSIDE the engine, you are describing?
Because before, you didnt get a spark INSIDE the engine?

What I understand, when running plasma spark outside, the spark plug gap of the plasma spark must be wider / larger than the spark plug gap of the secundary, initiating, LV-side spark plug. (You said then, the initiating spark plug gab must be smaller).

Now, the plasma spark is INSIDE engine and in a pressureized atmosphere. So we have to get a smaller gap. Maybe the gap inside (plasma) has to be more narrow than the gap outside (initiating spark plug).

Here is my material to this afternoon trials.

From left to right

1-? 11 pairs of 1N5408 (2 diodes in parallel x11 in series)

2-? again 11 pairs of 1N5408. Same schematic but with different displacement.

3-? 13 P1000J diodes in series.

I asked for 6A10 diodes and the hawser was:
Sales man: Which voltage?
Me:            Well 6A10 are 1000V aren't they?
Sales man: I have 600V rated.
Me             OK, give me allot of them!
Sales man: here you go, I only have 13.

Now that I look at the diodes I see that they are not 6A10 but P1000J diodes. I feel deceived...
I now see that this diode is 600V 10A DC 400A peak rated so its similar. BUT IT'S NOT THE SAME

If I ask for a lime I don't want to be given a lemon...

So any way, lets see the results later on.

Sounds like a voltage issue.  Or not enough current to maintain the spark.  Maybe we need ore turns or a better coupling to the engine plug.

@Remoireturn:
Dont know how much time it will take...we will see. But i am sure it will take less time to charge then for me to actually receive the cap...LOL

@Super God:
This is  a quote form cap70....

QuoteIf you increase number of turns on secondary it reduces the current flow of LV. with more number of you can see good plasma spark but the effect of water gets reduced. Explosion is weak.

But i think i will try it just the same....i got nothing better to do while waiting for my caps!!!!
