I bought my S3 analyzer about 3 years ago. It's bailed me out a few times on tough intermittent problems. Last time I used it was on a Swift 5000 that would fail every 3 days consistently. This went on for a couple of weeks. Hooked up the analyzer and found a flaky Governor switch. No rhyme or reason for the 3 day failure interval. I guess it was just the elevator screwing with me.
