Weird Computer Failures

[sula]

The tread below reminded me of something that I just cannot understand. We have two cat eye computers on the bike. I have never had a problem from cat eyes except last year while on tour first one then the other computer started blanking out. Just as if the batery had failed. We ended up carrying a bag of spare batteries and swapping a couple out a week. This seamed to happen mainley on long decents. I have no explination. Is it possibel we were building some sort of static charge up from braking.

Any similar experinces suggestions or solutions greatfully received.

Hard wired or wireless?

Hard wired. Why? got any idears

Which model(s) and does each computer have it's own pick-up sensor or are they working off of a single pick-up with spliced signal wires? How much distance is there between each magnet & the pick-up sensor? At what speed did they both go blank? Did the computers recover when you did a reset all without changing the batteries?

To be honest I forget the model. Middle of the road cat eyes. No splicing or any funny buisness. One set up to back wheel one to front. Only way to get them working was to pull the battery out and put it (or a fresh one) back. Sensor / magnet distance was pretty standars 3-4mm gap kind or range. As for speed it seamed to happen mainely on long down hills. And some of the down and up were significant we were climbing through the mountains of south west china at the time. If it had been just one computer I would have just written it off as a bad one. But both acting the same seams odd. Funilly enough when I got home I continued to use my computer on my single where it was fine. Although I did blank on me once on the tandem. I cannt be to categoric about this as was run over while out training shortely after comming back and havent ridden much since.

Bizarro... Can't imagine any kind of static charge build up being at the root of it and since it happened to both at the same time the probability that it was caused by moisture penetration seems unlikely as well. I suspect it may remain a mystery.
