The kill switch can not draw down power, so you can cross that off. Sounds as if there is a short as suggested above. You will need a multi meter w/ a 10 amp test mode. The battery can be charged overnight w/ an old camera wall adaptor, or a lap top adaptor, ect. as long as it has 12v output. Just cut the plug, splice the wires to a pair of aligator clips, and you have a "poor man's trickle charger. You can then hook the ammeter in series off the batt. to the positive cable to see if you do indeed have a current draw. (should be 0amp) unless there is a digital clock on your console then you will see around 5 milliamps. If all is good there check the batt. voltage w/ the bike turned off. (should be 12-12.8v) Start the scoot, and you should see 13-14.5v. If not you have a faulty stator or volt. regulator. If yours is a 4 stroke, the cdi is a dc fired unit and will not run. Check these out, and look for the service manual on line,(there may be a link to one on this forum somewhere, try the search feature). the manual will have some basic resistance values to compare for the suspect parts. Please post back so we can follow. It may just be a disconnected plug somewhere, but you will not know until you get into it further.
