AC cdi units like the one you have there require an ac input of several hundred volts.
This is normally supplied by the bike magneto.
Better to go to the dc 12v version.
There is a write up I did in the link below...in there is a pdf (post #19) of all the different cdi units with dagrams etc.
Thank you very much
