hello Carb, you have 6 diodes connected to your stator now, you should now have 2 wires that is dc ouput. you take the rotor wires and hook them to the 2 wires comming from the diodes, this will jump it to full power. to regulate, you add a fet between a wire comming from the rotor going to the stator.
i have been pulsing my rotor lately, i have found it to work very good as well. the self powered way works great, but you have to baby it and change freq all the time, i think i will be moving on to pulsing the rotor even though it uses about 2 amps more to do it this way, i feel its worth it not to have to baby it when its running. the circuit i use to pulse the rotor is just like the dave lawton circuit, but i use around a 4 uf cap, i will have to look.
