Hello everybody,

I have been following this discussion with great interest. I have tried the recovery coil and as you have said the battery voltage will remain constant for a while but then it drops and the whole process seems to damage the battery. So it seems to be a bad idea to flipflop the primary for a longer time. Rick never mentioned a longer test. I think that in the end it will run down....but I would love to be wrong here.....
As to the voltage spikes: Isn't there a phase difference when you use the NSNS magnet system? I think you might get a phase difference between the voltage on the negative side of the circuit and the spike being generated in the recovery coil. depending on where you put the coil on the circumference of the wheel. This way the voltages in the circuit and in the coil might add to each other..???

I strongly recommend to everyone to test at least a 24 volt setup of the bedini machine. I run my machine (five coils) on 3 batteries (36 to 40 Volts) on both sides. everything works much better this way, I use the 3055 transistors and all you have to change is the setting of the trigger pot (wire wound is a must here). watch the rotor speed though. I try not to go over 200-220 rpm on my bike rim rotor.

I wonder if some sort of lockup also happens when one swaps batteries in the setup without a pulsing cap. The output batteries fill with the radiant and with my current setup I seem to be able to swap batteries only as long as I stay with two very well charged batteries. In the 13 to 14 volt/battery range.

A good way to measure the point where battery swapping is best done is to look at the sum voltage between primary neg and secondary positive pole. This drops at first -the surface charge dissipates- but then goes up - the secondary will charge a bit faster as the primary goes down. Lead acid batteries have these funny discharge curves where they can stay at a certain voltage for a long time and then they will suddenly drop. If you look at hte sum voltage these non linearities cancel themselves out somewhat. I can do this swapping several times and then the batteries seem to "lock up" the secondary just won't charge anymore.
I have tried the recovery to a different battery by using an unused trigger wire in one of the coils. Just a FWBR on the coil. That seems to work but it slows down the charging in the rest of the batteries.
There is still a lot to learn for me on these circuits....

I think this forum is the best one around and having DR Lindemann at your sides certainly helps! Keep up the good work!
