RE: Opensource CDI ignition
Reference (above)... Oatley Electronics ..... Surplus fluro inverters for ferrite trigger transformer ($4.00) part No. CFLINV
Disassembled one unit to see what parameters were. It has an output winding of 380 turns 33awg. I removed a second unit and left the output winding and insulation in place and re-wound primary and feedback. Seems to work ok on testboard but not sure of effect on available energy to main capacitor. Getting around 500Vdc
