Water Sparkplug

The NPN's were 2N3055 and the PNP's can be any moderate power PNP transistor that you have laying around.

Do like this:


If you put the diodes like in the upper part of the picture and there is no spark, then your HV is of negative polarity, if there is a spark, then your HV is of positive polarity

i think my hv is negative since i connected the spark plug at the negative of diode. Like in the diagrams. The oscillator diagram that you used very simple. What are the part no of transistor that you used?

How to tell that the car run at negative or positive hv. When i put the diode string at negative side without inverter and capacitor the spark plug fires, when i put positive side spark plug not firing. Is my hv negative? May be i was wrong.

Ok, I understand now.
If your high voltage output from the ignition coil of positive or negative polarity? I would lose the inductor and put the diode string on the positive line and the other way around Did you use this on a running car or on a bench setup?

Here is what I am using and what has worked well so far:


But this is used only if the HV output is of positive polarity.
Hope this helps.

Hope this will help. Sorry about poor drawing.

Sorry, still not clear

ok i will sent the schematic later. Sorry.

Battery exploded

Im using an old version of nexus arc generator schematic in water spark plug pdf from panacea university. I changed the rectifier diode to full wave rectifier diode rated 15amp. MOT was changed with a transformer that only connected at the primary 12volt side. Hot wire connected to the transformer, and diodes string at the N terminal. Capacitor connected after the bridge rectifier before transformer. The L terminal connected directly to the spark plug. N terminal connected to the spark plug kathode. Hope u all understand

Maybe the file is too big. Users usually try to upload a large BMP file directly from paint, try to save the file as .JPG

don't see anything

i tried to upload the schematic but some error massage came out that says invalid address

Hi topangler81.
I am glad you did not get hurt, Can you draw a schematic on how you had everything connected just before the explosion?

here is my schematic.

be safe

Glad you didn't get hurt.

I hope everyone uses safety glasses and other precautions!
