Hello there, Scooters are just like vehicles. If the unit has been parked for a little over a year mere charging would not restore it back completely. The system would have suffered from general wear and tear.Here are a couple of things you might want to check:
Brake release lever disengaged. Engage brake release lever.
Key not fully plugged in. Ensure key is inserted fully into keyswitch.
Charger plugged in. Unplug charger from scooter.
Circuit breaker tripped. Reset breaker. If breaker trips again, it may indicate need for internal
repairs. Contact Dealer or a qualified technician.
Fuse blown in battery box. Replace fuse. Contact Dealer or a qualified technician.
Soft stop engaged. If key is turned off while driving, the scooter holds power for 1.5 seconds slowly decelerating to a stop. With key in the off position, wait for 30 seconds and turn key to the on position.
If the above mentioned happens not to be the problem then you definitely need a technician to examine the unit. Here is a link to the units user manual
incase you need instructions to carry out any of the above mentioned tips. Hope this support has been helpful?
