Leveling Jacks Inoperative

[Jeff Miller]

If the pump doesn't run, in addition to Frank's suggestions you can
check the motor solenoid (mounted on the motor) by shorting across
the large lugs to make the motor run, the solenoid is a cheap and
common failure item.

The solenoid gets its power from a microswitch on the top of the
leveler valve-body, a wire "basket handle" operates the switch when
any of the levers are moved into the extend position, this mechanism
can also be your problem (or the wires to the microswitch which can
be seen from below (battery bay).
