Steve always complains that folks will call him with a problem and after several suggestions they never call him back to let him know what the outcome was. He says this would really help the next guy.
Had an issue this winter where the tach started to flutter one cold flight and went to 0, The noise in the front let me know that it was the tach problem. Same flight the 496 also lost it's mind and could not find sattelites so I decided to come back to the barn and call it a day before something fell off.

Tach was replaced 600 hours ago and every so often it fluttered at high rpms. Pierce told me to take a look and possibly lubricate the cable. You can pull out the drive cable and what I found was rust and very dry. The spline on the engine side was worn down or sheared down. I got a new cable from Spruce and replaced it yesterday. The square end on the tach side was a workout to get into the tach which is high on my panel upper throttle side. I eventually pulled the tach connected it and reinstalled with the cable on. A second person might have been able to manipulate the drive but I was solo. Anyone with a trick I am all ears for the next time. Also cable is 4 inches longer than what it should be and probably part of the problem. New shorter cable at overhaul is on the list

Garmin 496 I have had it since my trip to Idaho about 6 years ago and what I finally realized was the date and time was not right. I corrected both but within a shorth preriod it would lose time. Also the data was 6 years old. So after spending a fortune updating the data $399 I purchased a new battery for $38 and she is good to go.

So Steve, Thanks for the help and this is what I found for your memory banks!!
 
Dry-slide works wonders for sleeved cables. Sorry but it won't cause shrinkage.

Ps. Once upon a time I wouldn't have traded my 496 for anything, but times do change. This weekend I flew in a rental 172 that had a 496 in it and after using a 796 for the last 2.5 years I felt like I was back in what SteveE tells me the dark ages were like...

No, Tim knows about the Dark Ages....Have him tell you the story about when he was one of the Knights of the Round Table.... True Story

My tach did the same thing - that little key that goes into the engine got a little loose where it was swaged, and over the years the housing nut backed off the tach, allowing the cable to separate. A little solder fixed it.

I am living in the dark ages - I use the 295 and the 496, more or less permanently installed in my airplanes. They are light years ahead of the stuff that was in the A-320, and way easier to use than the monstrous 430. I have not tried the newer hand helds.
