Bicycle Mechanics - Cateye Strada Cadence (wired) cyclocomputer acting up...suggestions?

My Cateye Strada Cadence cyclocomputer has < 200 miles on it. While riding today, it suddenly stopped reading the mileage. Then, it even stopped reading the Cadence. And throughout the ride, the computer haphazardly picked up the mileage, then stopped, and basically the same for Cadence.

I'm pretty sure it's not the sensor, as the magnets are very close to the sensor. I suspect it's the wiring. Question is: how do I find out which part of the wiring is causing the problem?

Or, should I be looking at something else?


Thanks!

Before you tear the bike apart, change the battery. Yeah, I read that it had less than 200mi on it, but it could have been sitting on the shelf a long time.

try cleaning the contract , use a rubber easer to do so.

+1 Clean the contacts on the mount and on the cyclometer head using a pencil eraser. DO NOT use sandpaper or other harsh abrasives. If you have some, a thin film of silicone grease will protect the contacts from water and further corrosion.

Yes check battery and make sure the unit is making good contact.
