Good job! I didn't have time to work on the injector today. I was going to go into the shop tomorrow AM for a while and try to sort it out but I now have to captain a boat tomorrow morning so maybe in the PM I will swing by the shop and finish.

Hi All,

Yet another sad day for me. As i could not get the plasma spark on my plug using the Cap70 circuit. I would be glad if some body can pin point the error. I did the following:

1. Did not used the pulse pickup coil and attached diaod / transistor as i have taken the HV directly from my bike, which already has the Pulse pickup coil, capacitor and ignition coil.

2. Primary coil 32 turns using Aluminium / copper wire of 16 gauge and on secondary side it was 12 turns.

2. Rest all circuit is same as Cap70 circuit.

I had following obervations:

1. The insulated wire coil (12 turns) was getting the charge from ingition coil and returning the same to the earth side of the plug. Since the positive and earth were shorted out hence no spark at plug when place in the circuit.

2. No heat is observed at coil or any other component.

3. When removed the ground connection on the plug coming from the coil there was a spark on the plug as this time there was no sorting and plug was getting the HV from ignition coil.

4. When the wire connected to the earth side of the plug is removed and taken to near to the bike body then it was showing the spark. I think the positive charge coming out from the plug and going to the other end through insulated wire, but was not in position to energize the primary coil having 32 turns.

I dont know the mistake i did. Any help in this matter is highly appriciable.

Hi All,

Although i could not get the first plasma spark using the Cap70 curcuit but still i am thinking about various solutions. I hope  i will get the desired help to get the first spark.

I was thinking of removing the ignition coil and capacitor from the system and was planning to use the Color monitor flyback transformer. The reason for using this was on following account:

1. It modulates the power at 15.7 Khz which is close to the 14.3 Khz (the best frequecy described in Stan document to detonate the water).

2. It has constant and good high voltage at all the time but unfortunately with low current.

3. We can use the point system to retard / advance the ignition timing and this switch will be on 12 volt side.

We can use the coil side circuit of Cap70 to add up the current. I think this can give us the desired result. One schematic for the same is enclosed herewith, would like to have the view of the members.

Hi Praveen!

Here is a fyu things you could think about.:
- I'm not sure if its mater but try at with resistor free spark plug on both side.
I was able to get that circuit fire with plugs like that.
- On my mover i have a coil and two magnet on the flywheel so I guess it's sparks twice rapidly one after a another, if your bike has that kind of ignition that may be a problem. I don't know because never tried that circuit with the mover.
- Your primary is the one with 12 turns, the secondary is the mag wire with 32.
Always the primary coil gets energized first than the secondary from the primary's magnetic field.

Hope it's helps!

@Xbox,

I've found a champion spark plug made for boats. ( L76V)... It is resistor-less, and it doesn't have a normal "J"
cathode.....It arcs in a 360 radius.. This may help if the plugs cathode is getting fried ?

Has anyone used one of these plugs? ......I got mine from Wal-mart for $2.00 on clearance......

Let me know what you think....................
