I posted this in the General section, but hardly got a response. Perhaps this forum will be more helpful, it usually is.

My Cateye Strada Wireless has been acting up lately. It will go just fine for a few miles, then read 0.0 for some time, then it will turn off, then come back on, then freeze at some random speed I was going, then go back to 0.0, then go to a different speed, etc. All in one ride.

I replaced both batteries, same symptoms.

Went on a ride the other morning, and it worked flawlessly the entire ride. Then I went out the other night, and it acted up again and I'm thinking hmmmmmm why only at night?

Last night, I tried something new, I turned my headlight off while I was riding, voila! almost instantaneously the computer read 21.2 and was fluctuating as I slowed/sped up. I turned the light back on and it went back to zero.

The light is a Niterider MiNewt 600 and I was using it on low power. Before last night, I had been using my Niterider MiNewt 250 on high power, and had been using it for 6 months with no issues, until about 1 month ago.

At first, I thought it could be something to do with frequencies, but then I wondered why I rode so many trouble free miles with the same light and computer. I'm now starting to wonder if it could have something to do with the heat... about a month ago it got really hot. Or perhaps the battery in the computer is low/damaged which could cause it to be more vunerable to issues like this?

Help?! It's driving me crazy. I tried moving everything around and it still didn't work.
