Hi stevie,
What you see there in the pic is:
Big multimeter measuring the voltage across the rotor
small multimeter measuring the current passing through the rotor
Then I use the oscilloscope to see whats on the output @across the cell (shown in vid)

Where should I hook the diode?

Can you put a video up on youtube for us?

I will post one as soon as I make it work in self sustaining mode

when you get it going, you should post the volts across the cell leads not the rotor leads, if we know the amps you use going into the rotor from that stator that would be good to.

when you're self sustaining you're almost there.

the last least important part is to measure the amps pulled by the cell, 15 amps is not bad.

when you're all done with that, you should tune into resonance, assuming you have everything hooked properly and your circuit is producing good with a timer cap labeled 103k, and a spike remover connected to the rotor to help regulation.

the 10k pot is the pot you use to regulate, leave the 47 or 50k pot turned all the way to the proper side at the lower half of the freq.

i just seen your cell in the video, there's no way that cell is to much for the alternator. that will be a good setup if you get it going...

please measure on the wfc leads.
Put an ampmeter there and a voltagemeter.
Its best to add on that voltmeter a diode in serie with your meter.

keep on going the good work.
Yr setup looks ok.
As hydrocars said, is the voltage and amps on the rotor not so important, except for not overloading it.

Hi guys, I think i got it with the self sustaining
The cell runs beautyfully now,better than ever I`have seen it runnin, and there is little load on the drive motor.
Now the cell is running by itself ! wow, only kinetic energy from the driver motor is needed.
I am going to buy a clamp ampermeter dc/ac to find out what power is consumed from the driver motor.
Here I posted some pics and another video :P
I did not fiddled too much with frequencies. Better production and efficiencies are possible.
By the way now I think I`m getting the waveform. I dont think it is good as yours hydro and stevie but that may be a mosfet issue. I am using an IRF640 for now. Voltage of the squarewave is peaking at about 10v @across the cell, current still to measure.

im so happy that you got it going! the wave form you're looking for will be square waves with harmonics in the top, it will look like strings. it is best to look at this on 1 channel of your oscilloscope.

Good Work!!!

this is the wave you're looking for. it will look very similar
