Power Seats

CIRCUIT OPERATION
There are three reversible motors that operate the Power Seat. The front height and rear height of the seat are operated by different motors. Each can be raised or lowered independently of the other. When the Entire Seat Switch is pushed to the "UP" or "DOWN" position, both motors run to move the front and rear 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 LH Power Seat Switch to ground G311.

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 ground G311. Both motors run to drive the entire seat up. A similar action occurs to move the entire seat down.

Each motor contains a solid state self-resetting circuit breaker to protect it from overload.
