The reading that you have are the same as I got but they will not hold in operation. The pots sample and mix the signal to operate controlsand graphics. Found the problem when I dissembled the gimble. The gimble was holding presure on the pots that wore the shafts anought to weaken tenshion on wipers.
Called GP support and the got a little smart with me and said that the controller was out dated and to buy a USB that they did not give out information to on parts to key pushers that don't even fly; Then gave me the net support EMail. GREAT GUY!!!!!!
PC messing up again get back later if I find more info.
