Thanks for that, it was on the LCGB site a few years ago but I lost the link to it. I believe the idea is that normally only one of the AC pulses is used to charge the capacitor in the CDI. The ides of the gizmo is to store the other pulse and then deliver it together with the original pulse and thus supply a higher voltage through to the HT coil in the CDI and thus give a bigger spark. Please correct me if I have that wrongThanks for that, it was on the LCGB site a few years ago but I lost the link to it.

A capacitor cannot convert AC to DC, the circuit above would allow the capacitor to charge when the current is flowing in one direction only (positive or negative pulse)due to the diode. I'm not saying it won't work, I;m sure it does 8-)
