If the batteries have not been used in a while, they may have gone bad. The batteries contain a gel that needs to have current run through it on a regular basis (at least 8 hours once a week) or it will solidify. If you attach the charger, what will most likely happen is the green light will either stay green or go to green after a very short time. The charger will indicate the batteries are full, but instead of being full of pwer, they are full of crud. Your warranty will most likely not cover replacment as this is due to customer neglect, but your insurance may still cover the replacement if you can wait for the process to go through. Otherwise, you will need to replace the batteries on your own.
Good luck!

First your going to remove the deck.
Take off the chain tensioner
Next remove the motor and put the chain around the gear
Put the motor back on the scooter with the chain on
Then take the rear wheel off and put the chain into the gear.
Put the rear wheel back on along with the chain tensioner and deck
Your done!

Note: the reason why I say you have the remove the motor and wheel is the get the chain on. So you may only have to partial remove the motor or tires to get the chain on.
