no im not exacty sure what happend to it. The time the scooter was stolen and they tryed to short circuit some wires... that might have destroyed the regulator/rectifier... also i was trying to short circuit the scooter my self because i wanted to se if it realy was that easy to start the scooter without a key... and i might have connect the wire wrong because the fuse did blow at one point so i think it was the thives or my self that broke it.
The scooter worked for some time... maby some days after that because the batteri still had a charge so you could still drive the scooter for som time even when the regulator/rectifer broken.
