Power Seats


Each Seat Motor Assembly has reversible motors within the same housing. The Seat Control Switch determines the direction of curent flow. The direction of current flow determines the direction of current flow determines the direction of motor rotation, which controls the seat adjustment direction.

A circuit breaker protects each motor from power that is applied when the motor is stalled. The motor stalls from either mechanical failure or running to the limit to 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 circuit is grounded when switches are at rest.

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