I havent gotten around to any more testing yet (house hunting is keeping me busy).
But been doing research.
I looked at your photobucket. I figured i would just clean the brass post, but I see you seperated the entire sensor. I don't wanna break it on accident. Would you tell me how you seperated the sensor to get at the internals? I am envisioning myself pulling/twisting or something and then cracking the plastic plug.
Been awhile...........
I used some combination of screwdrivers, small chisels, needle nose pliers and a dremel to uncrimp it.
