Roger, sometimes I need to choose my words more carefully. In one extreme position, the center terminal of the pot is connected to one of the other terminals. At the other extreme position the center terminal is connected to the opposite terminal. The technician should remove the center terminal from the circuit board and then connect a jumper from the the circuit board where the center terminal was connected, to where one of the opposite ends of the pot are connected. Which end, needs to be determined first by the technician.
