Modern Vespa

Hi everyone. I've got a no spark S50 2 stroke year 2009 and ordered a new CDI unit which has coil included. Whilst waiting for this to be delivered I noticed someone posting about these S50's having more than one fuse. But the manuals say not. Anyone know if there is another fuse protecting the ignition circuit (apart from the 7.5A next to battery)? Anything else I should check if new CDI doesn't produce spark? So far battery checked, spark plug changed, condition of HT Lead checked and all connectors checked. No kill switch on this one. Starter turns engine over, lights work just no spark! Advice appreciated.

Just the one 7.5A fuse.

Some of this ~2008 Piaggio tech info might help: https://manuals.wotmeworry.org.uk/useful%20info/Info_manual_1.pdf

Thank you that's a really clear document. I haven't got that one. I think I will also investigate if there is any test I can do on the stator.
