Russ,
I think we got it with a slight clarification. When I first push the extend or retract button the motor starts and there is a slight delay before any movement. I think this delay is the time it takes for the pump motor to start, pressurize the system & open the pressure switch.
Hopefully this thread has clarified how & why our slides operate & sequence the way they do. It should help in any future troubleshooting.
Here is the HWH owners manual for the 680 series leveling system & slide rooms. On page 18 is a picture of the slide room manifold and where each solenoid that controls each slide room function is located. The solenoid styles have changed over the years, but they all function the same--they are interchangeable with each other. Their function is determined by their position in the manifold and electrical connection. This manifold and solenoids are located in the first compartment on the driver's side.
Back to the original question of the locking pins punching a hole in the roof of the slide: Since there is nothing in the 680 series to identify where the top of the slide is, the locking pins deploy when the bottom is either fully out or fully in. If a locking pin punches a hole in the top of the slide, you need to determine why. It may come down to a slide room adjustment, the chassis of the coach being in a bind or something physically keeping the slide out of position.
