Bryan,
 
While the plane is on jacks, one test would be to open the = dump=20 valve (relieve all pressure) and see if the pump runs in the = gear down=20 direction, but not in the up.  This would suggest that there is = some=20 sort of "squat" switch.  If so, the most frequently used = one=20 relies on pitot-static pressure so the gear cannot be retracted = until 70=20 KIAS is exceeded.  Some simply bypass the switch with a jumper = when=20 doing the gear checks while others may have installed a bypass = switch,=20 sometimes hidden behind the panel.
