Driver's Seat

When the operator selects the FRONT VERTICAL UP function, power is passed on the F37 circuit through the closed contacts in the switch to the P19 circuit. The P19 circuit connects to the motor. Ground is provided on the P21 circuit back to the switch. A ground BUS bar internal to the switch then connects it to ground on the Z3 circuit.

For FRONT VERTICAL DOWN function the circuits are reversed. P21 is the feed, and P19 is the ground.

When the operator selects the HORIZONTAL FORWARD function, power is passed on the F37 circuit through the closed contacts in the switch to the P15 circuit. The P15 circuit connects to the motor. Ground is provided on the P17 circuit back to the switch. A ground BUS bar internal to the switch then connects to the Z3 circuit.

For HORIZONTAL REARWARD function the circuits are reversed. P17 is the feed, and P15 is the ground.

When the operator selects the REAR VERTICAL UP function, power is passed on the F37 circuit through the closed contacts in the switch to the P11 circuit. The P11 circuit connects to the motor. Ground is provided on the P13 circuit back to the switch. A ground BUS bar internal to the switch then connects to the Z3 circuit.

For VERTICAL DOWN function the circuits are reversed. P13 is the feed, and P11 is the ground.
