Step 1
Check that the outlet that you are using for the battery charger is working. Plug a lamp or other small appliance into the outlet and see if the item works. If the outlet operates with a switch, check the switch to make sure it is in the “on” position.
Step 2
Turn off the controller power. The battery will not charge as long as the controller power is on. When using the onboard charger, the freewheel lever also must be in the engaged position.
Step 3
Lift up the seat and ensure that the battery connectors are secure. Sometimes a sudden jolt from stopping too quickly may cause one of the connectors to jar loose.
Step 4
Look at the position of the charger switch to ensure that it is operating. The switch has a “zero” and a dash mark. When charging the switch should be to the dash mark side. Look at the two LED lights on the charger. Both lights should be illuminating when charging; if they are not, check the connections at the chair. If the wires are connecting securely, replace the portable charger.
