Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Computer quit, now working again

Wife and I started out today on a ride. It was extremly foggy out so it was very damp. We rode about 20 miles and it started to sprinkle a little. I looked down and my computer was reading 0. It came on and off a few times but was reading from 4 to 15 mph and all over in between. I had been riding at a steady 20 mph pace for the last 10 miles. Got home and found out both computers, my Sigma and her Cateye had both started to cut out at about 20 miles. We rode a total of 24 miles, I had riden this route many times. Neither one was working when we got home. 1 hour later I checked and they still were not working. 3 hours later they are working fine again. Neither of them got soaked at all but they were quite damp. Is this normal? I have riden in the rain before without any trouble.

Try taking the computer off the mount and wiping the leads with alcohol.

Sometimes rubbing a new pencil eraser over them, then using the alcohol works best.

I'll try cleaning them. It just seemed strange that both of them did the same thing at about the same mileage and then they both dried out and are OK. I'll clean both of them.

OP - My Polar has locked up a few times. There is a reset on it; when I reset it works fine. I think it has trouble ordering the files inside when I delete/add, etc.

I had this same problem with my wired one. Cleaning didn't help....I replaced the base unit/sensors (at a pretty low price) and everything came back okay.

Just went to clean it. There are no contacts on my Sigma. The wire runs up to the mount but no metal contacts. Nothing to clean. I removed the battery and checked it. 2.98 volts. I reset all the parameters also. There is no low battery signal so the battery should be fine. Raining right now so I can just spin the wheel in the garage. It is working but it seems a little off on the mph. I'll have to check when it dries out a little.

Did you hit any potholes? Mine has dropped out because the sensor shifted position after rolling over some particularly lousy pavement.
