III. YOUR POWER CHAIR
Electrical Components
The electrical components consist of the controller assembly, the batteries, and the motors. The batteries, motors, and
controller power module (if equipped) are located on the power base assembly. See figures 6 and 7. The controller is
located on the seat assembly. Connectivity between the controller and the motors, the batteries, and the battery charger
is provided by one or more wiring harnesses.
Controller Cable Connector: The controller cable connector is where the controller plugs into the power base. Each
controller uses a different type of harness. If the controller has a power module in the power base, the connector is a small
communications-type connector. If the controller is integrated, then the harness has a large 9-pin connector. Regardless of
which type of controller is used, the harness must be secured to the seat assembly and not allowed to drag on the floor.
Battery Harness Connector: This is where the controller connects to the battery boxes.
