it shouldnt do that really if you left it for a month i could understand it but 3 days is extreme,firstly what make of battery have you got as alot of them are crap.i cant name them but ill name the good ones
exide/yuasa/mf/varta /yumicron and maybe a few other i cant think of .tell me this if you have the negative lead on the battery and disconnect the positive lead and just touch it on the positive terminal on the battery with the battery charged up do you get a spark?when i say touch it i mean do it very lightly as the spark will indicate how much current is bein drawn out of the battery if its a very small spark then the drain is low maybe as bb says it may be the immobilisers current draw ,but if its a reasonable blue spark then there is a short to earth somewhere.let us know what you find out and we will help again to solve it.ps bb is right peugeot dont make a good scooter :( the cheaper ones are the best like vivacity and zenith/buxy/speedake/rapido all budget mopeds but simple and easy to fix (without immobilisers)electrex is the non immobilised cdi maker for peugeot scooters.check out there website.
