Good evening in the round, I bought a Benelli 49x BJ 2008 ac a few weeks ago (motor, Lima, Cdi… should correspond to that of the pepe). It is an alpha technology 25 km/h Drossel cdi installed (4pin +2pin plug, on the 2pin plug but only the black/red cable from the handlebar switch goes in). With this cdi starts the scooter and starts well (even without battery, therefore ac). Now my problem: I would like to use a 45km/h or an unrestricted cdi. Have now eight new cdi’s bought and tried (all suitable for the model according to the supplier) and with all of them, after the first e-start attempt, the 10A main fuse on the battery flies out and without a battery no spark comes. Unfortunately, I can’t get an original cdi anywhere and I don’t know what this looks like or what has to stand on it. I checked the wiring, is according to the circuit diagram. CDI and plug see picture I also have a multimeter at hand, but I’m not an expert in electrical engineering. I can measure the end of the motor by the battery about 14V, without the engine it has just over 12V. I am completely desperate. Can anyone help me, why no other cdi works? MfG
