I just noticed that you don't have the D1 diode marked in the schematic??? I was just wondering cos I have got my dual coil working fine now but have included a 1N4001 per transistor...

I can't find any where that says what this diode is for but am i right in guessing that when the power coil fires, its magnetic field induces a current in the trigger coil in the opposite direction to the current induced by the magnets and thus quickly turns off the transistor as soon as it opens which creates the sharp pulsing? So this diode allows the "backwards current" to flow freely while forcing the induced current from the rotor into the transistor.

If that is the case then only one of these diodes should be needed even if you are using multiple trasistors. Is there and advantage or disadvantage of having more than one diode?

and while on the subject of diodes... the 1N4007. I noticed in one of bedini's diagrams that he had a "diode cluster" (about 3 i think) going to the positive of the charging batteries from each transistor. Is this to reduce the impedance of the radient? Has anyone else used more than 1 diode coming from the collector?

and somebody mentioned in another thread about using a ground wire connected through a diode to the positive of the main battery. Cant remember which thread it was. I don't have the luxury of a garden (living in the penthouse! lol) so I have connected an 18" radio antenna to the postive in the same fashion and it pulls .024V from the air into the battery... Tried a 4 foot antenna as well but the voltage was the same so just using the smaller one. Do you know how many volts were coming from your ground wire?

A ground wire seems to make sense since , as bedini found out through his pendulum, radient energy alone can't keep batteries charged so a ground wire could possibly feed the batteries the extra electrons. Again this is all guess work!!! Anybody have some insight on this?
