Charge the batteries of your scooter, before you troubleshoot to identify and repair a problem.
Check the wiring of the batteries. The batteries should be wired as follows: red to positive (+) and black to negative (-).
Replace the batteries if they will not hold a charge. "Batteries over a year old may be defective," warns Pride Mobility.
Listen for a beep code. A series of beeps may help users identify problems with their scooters. Two beeps indicates low battery voltage; users must charge batteries until they're fully charged. Five beeps indicates a solenoid brake trip; push the freewheel lever to the drive position. Six beeps indicates a throttle trip; release the throttle control lever, then reinsert the key.
