Do u have a diagrams of it? How you got 30 Amps at only 1.5 v? And the voltage was peaking after turn off?
Fabio, the leftover voltage is heavely depending on how much voltage you put in.
My alternator was unregulated. So it hit the wfc with 36v pulses.
So when you pulse the rotor and because of that also the power to the wfc, there is a short periode where the wfc acts as a capacitor.
Normally, you out max 5v to the rotor...
The charge of the wfc was after charging, enough for charging the rotor...
