    My friend has aChituma CTM250-3 Fastran

    - VIN: LE6
    - engine: 253FMM0660400xx

    He would buy a secound CDI Unit. He has switched the Unit with another friend who has Xintian Kinroad with 253FMM. And the CDI's doesn't worked.

    The Chituma model is not common in Poland. Gives there any advice how to check what CDI should he buy? Jinlun, Lifan ?

    Is it square or rounded plug
    Basically only 2 types but many different qualities
    I was in Guangzhou and saw timing adjustable units but must buy at least 100 pieces
    I wanted one as simple but they wouldn't sell it

    DC or AC-cdi ?
    Most 253FMM CDI are as CA250 /Rebel (2.2µF capacitor) BUT some cost-down maker are using CM125 electrics (1.5µF capacitor) ...

    EDITED
    After research http://www.mep.gov.cn/image20010518/497.pdf 253FMM from CTM250-2 is a Zonhshen which = 92 | 14 above (CDI had a side stand s/w input. MOD the electrics to accept normal CA250 clone ... Kinroad etc )
