No where in Stan's documents do I recall him pulsing the alternator with a pulsing circuit. The only pulsing the alternator gets is 60 Hz AC from the wall rectified into 120 Hz DC into the rotor, but this is not meant to be something fancy, it's just what comes out of the wall. Kevin is doing some things that are not 100% in line with Stan, which is fine, it's great.
Are you using distilled water? sending 100 volts and 1 amp to tap water should give you something?
Not sure if you are using those capacitors, I'm not sure how they are supposed to help, but I know stan used bifilar chokes that have capacitance.
