Dick,
I had an 89 Contessa and it had 4 levers on the floor, one for each jack, that would manually be operated for extend and retract. It was a simple system with an independent set of leds on the dash that were calibrated to sense level and changed status when a quadrant of the coach level was correct. It was made by HWH as I recall, and the retract was by return spring when the lever opened a valve. Not sure if things changed by 1991. If you are not retracting and it is this system you could have a weak spring or possibly a bent ram. These coaches if the rear wheels were raised enough to lose ground friction they could fall off the leveling ram and the jacks would pivot (not in a controlled manner) in the direction of the fall with a crash. That could have damaged a RAM before you got this coach. If it is the same system, this coach could not go through all these years without that happen a number of times.
As I recall HWH was written on the floor plate so I am thinking you may have a different system.
