Power Seats

DESCRIPTION

The Driver's Seat Motor Assembly - has three reversible motors within the same housing.

The Driver's Seat Control Switch - determines the direction of current flow through each motor. The direction of current flow determines the direction of motor rotation.

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 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 Circuit - is grounded when switches are at rest.

OPERATION
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.
