I was experiencing constant Tilt and Recline problems due to faulty mercury tilt sensors/switches. I was getting stuck in positions that caused me grief or I could not travel up even slight grades. The switches are supposed to be a safety feature, but they were putting me in jeopardy instead. 

There are two mercury tilt angle sensor switches mounted to the frame and connected to the TRAM (tilt, recline, actuator) module via 2-pin connectors. My fix: Remove the back cover to expose the wiring harnesses. Trace the two sensor cables to where they plug in to the TRAM module. Cut the two cables about 6” from the connector ends. Strip back the cable insulation to expose the two wires inside, a black one and a white one. Strip back the insulation on these two wires and twist them together (or crimp them, solder them, etc.). Test the chair to make sure it works OK. Then use electrical tape (or shrink tubing, etc.) to insulate the exposed wires. Repeat on the second sensor cable.

This fixed my chair and I no longer have problems with tilt and recline getting locked up.

If your PWC is still under warranty, my fix could invalid your warranty. Others may wish to have their PWC dealer replace or adjust the sensors.
