68 Superior Table inop . Had two issues electric motor was bad, and one spool valve was frozen and would not activate the micro switches on the rt side. When you pull the cable out the spool valve hits the out micro switch and unlocks either the LT or RT lock jaw., when you push it back in it hits the in micro switch, these two switches active 2 solenoids that turn the motor clockwise and counterclockwise. When the table comes back in it hits the center button on the jaws and locks itself. There are two limit switches front and rear, that stops it coming out and back in. There are also 2 switches on the seat bottoms. The seat back has to be forward for it to operate, some also have door switches that to do the same thing. There is one more switch under the lock jaws, when the manual lock lever is used it opens the switch and cuts all power to the switches. All the switches are in series; the wiring diagram makes it all make sense.
