PEUGEOT TREKKER 2002 50CC, NO SPAARK at plug.Bought running, told it has a cdi bypass fitted. but now no spark, done tests, have signal from flywheel, have relevant live feed and earth so suspect cdi, my dilemma... ordered new coil & cdi unit, new cdi is 5pin about 4inch by 2inch (retangle), not one on bike, no plastic 5 pin plug. BUT, on front of scooter (all panels removed) there is a metal unit about 5inch by 3 inch, with cooling fins and a block connector same as bypass cdi, I cannot find description or pics on internet, wondered if u have any ideas,so have I bought cdi unit of the wrong Type? if this bike has bypass cdi can I rewire the one I Bought?
