Have a new-to-me '07 9660sts. Remembered hearing of problems with moisture sensors. My '00 9650sts had the meter on the elevator, with a lid I could remove and wipe off the inside plates. Never had a minute's worth of problems with it. Don't know what needs to be done on this one in the way of maintenance, etc. No info on it in op manual. How does it come out and/or apart? How often does it need to be looked at? Thanx for all replies.
