Partner R417T recently came with a broken CDI unit. I tried to get this unit apart to take out pulser coil and exciter coil for reuse. But this pulser coil was also broken in this work so I winded 350 turns at the same place of the iron core. The schematic is very simple and well known. Incidentally am using a 1 microFarad electrolytic capacitor but it's not for this kind of use, film capacitor is better for this.
