Scooter blowing fuse

[Shadowfire]

Most likely -> wiring to/from the coil (or some of the other wires bundled with it) is damaged and shorted to the chassis (or each other), and moving the wire has (temporarily) stopped the wire from contacting the chassis.

Less likely -> Something on the coil assembly itself shorted to the chassis.
Look for damaged insulation/broken plastic on the coil, especially where its attached to the frame. Check the wire leading to the spark plug too.

It's also possible (but extremely unlikely) that the coil itself has an internal short.

You're basically looking for anything wire that has exposed metal which could short out, probably with the frame of the bike.
