Entire Seat Up or Down
When the seat switch is operated in order to move the entire seat to the up position, battery positive voltage (B+) is simultaneously applied through the front and rear vertical motor up switch contacts and the front and rear vertical motor up control circuits to both vertical motors. The motors are grounded through the front and rear vertical motor down switch contacts and the front and rear vertical motor down control circuits to both vertical motors. Both motors run simultaneously in order to drive the entire seat up until the switch is released. Moving the entire seat down works similarly to moving the entire seat up, except that battery positive voltage (B+) and ground are applied on the opposite circuits causing the motors to run in the opposite direction.
