Front Vertical
When the seat switch is operated to tilt the front vertical up, battery positive voltage (B+) is applied via the front vertical up switch contacts and CKT 286 (DK GRN) (left) or CKT 297 (DK GRN) (right) to the front vertical motor. The motor is grounded via CKT 287 (DK BLU) (left) or CKT 298 (DK BLU) (right) and the front vertical down switch contacts to ground. The motor runs in order to drive the front of the seat up until the switch is released. Tilting the front vertical down works similarly to tilting the front vertical up except that the battery positive voltage (B+) and ground are on the opposite circuits causing the motor to run in the opposite direction driving the front of the seat to tilt up.
