Power Seats


The Right and Left Seat Motor Assemblies have reversible motors within the same housing. The Seat Control Switch determines the direction of current flow. The direction of current flow determines the direction of motor rotation.

If power if applied when a motor is stalled, a circuit breaker protects each motor. The motor can stall from either mechanical failure or running to the limit of travel.

The FWD/RWD Motor drives the seat forward and backward.

The Front Height Motor drives the front of the seat up and down.

The Rear Height Motor drives the rear of the seat up and down.

The circuits are grounded when the switches are at rest.

The Seat Control Switch sends current flow to turn the motors clockwise or counterclockwise. If the 6-way knob is set to the UP position, switch 3 is closed. Current is sent through switch 7 to the Rear Height Motor and through switch 1 to the Front Height Motor. The entire seat moves up.
