How to Troubleshoot a Liberty 312

The Liberty 312 is a powered wheel chair that provides mobility if you are unable to walk easily. However, as with any mechanical device, there are problems that may occur that will need to be corrected. Problems with your Liberty 312 motorized power chair include the battery not charging and the chair not driving correctly.

Battery Not Charging

Check for loose connections on the battery terminals. Tighten any loose connections that are found by using the wrench.

Unplug the battery charger from the electrical outlet and plug it into another outlet. Check to see if the battery will now charge.

Replace the existing batteries with new ones. If the batteries are old, they may no longer take a charge.

Connect the power chair to another battery charger. If the battery begins to take a charge, the old battery charger is bad.

Not Driving Correctly

Check the motor release levers to see if one or both are disengaged. The motor release levers need to be engaged to drive the scooter.

Verify that the setting on the battery charger is set correctly and that the battery is fully charged. Charge the battery to see if the power chair now drives as expected.

Unplug the charger from the electrical outlet. You will not be able to operate the power chair when it is plugged into an electrical outlet.

Check the breaker on the power chair and reset it, if it has tripped. If the breaker begins to trip often, it is an indication that internal repairs may be needed.

Things You'll Need:

  • Wrench
  • Battery Charger


Clean the contacts on the battery if the power chair does not respond properly to commands.

Verify that both motor release levers are engaged if only one wheel turns when riding the power chair.
