CIRCUIT OPERATION

There are three reversible motors that operate the Power Seats. The front and back height of the seat are operated by different motors. They can be raised or lowered independently of each other. When the Entire Seat Switch is pushed to the "UP" or "DOWN" position, both motors run to move the front and back of the seat at the same time.

The Forward/Back Motor is operated by the Entire Seat Switch. When it is held in the "FORWARD" position, battery voltage is applied through the switch contacts and CKT 285 to the Forward/Back Motor. The motor is grounded through CKT 284 and the contact of the Entire Seat Switch to ground G305. The motor runs to drive the seat forward until the switch is released.

In the "BACK" position, CKT 284 receives battery voltage and CKT 285 is grounded. This reversed polarity causes the motor to run in the opposite direction and drive the seat backward.

The Front and Rear Motors work in a similar way when the Front or Rear Height Switch is operated.

To raise the entire seat, the Entire Seat Switch is held in the "UP" position. This applies battery voltage through CKT 282 and CKT 286 to the Rear Seat and Front Seat Motors. The motors are grounded through CKT 283 and CKT 287 and the Power Seat Switch to G305. Both motors run to drive the entire seat up. A similar action occurs to move the entire seat down.

Each Motor contains an Electronic Circuit Breaker (ECB). ECB resistance increases if motor is overloaded. Resistance returns to normal after voltage is removed from motor terminals.
