Raising the Vehicle

When a load is added to the vehicle, the vehicle body is moved downward and the Actuator arm rotates upward. Switch B closes in the Auto Level Control Sensor. After an 8 to 15 second delay, switch C closes. The coil in the Auto Level Control Relay is energized and the Relay contacts close. Battery voltage is applied to the Compressor Motor. The Compressor operates and pumps air into the adjustable shock absorbers. As the air shocks inflate, the vehicle body moves upward. When the Actuator Arm rotates back to its original position (± 1 inch), switch B opens, the Relay is no longer energized and the Compressor stops.
