Brick, I've got the same/similar system. I'm confused when you say "when I try to raise the jacks I only get a click". If you are talking about retracting/closing your jacks, there is no electrical involved at all. The jacks raise/close via the springs which pull them up. There are sensors on each jack that indicates on the control panel when a jack is extended. That light shuts off when the sensor senses the jack in the up/closed position.
If you are saying the jacks will extend but as soon as they begin to pick up the load/weight of the motorhome they stop, then that would lead me to think the pump is weak, low ATF fluid or there is an electrical problem ie low battery. Please give us more info and we'll see what we can figure out.
