I recently installed the GSC-10. In just some basic testing, I noticed the red indicator was working consistently with the pedal stroke, but the green indicator would work for a bit with the spinning wheel but then cut out completely. I would hit the reset button and see the same behavior repeated (worked for a bit then cut out). I tried various things with moving the magnet and arm but in an indoor test (me simply holding the bike up and getting the wheel spinning) it was inconsistent. I paired successfully with my Forerunner 410 so I decided to take it for a spin to see if it was happy while I was riding. It appeared to be.
Now I am seeing some inconsistency in how it is performing. I had one or two rides where speed and cadence were sensed fine. Another ride where only speed worked (maybe it was using GPS for that?). The pairing appears fine. On my ride on the trainer this morning, nothing worked (I hit the reset button but it didn't make matters better). I was on a Kurt Kinetic trainer for this morning ride and I did read something about trainer magnets screwing things up so I'm not sure if that was the issue.
I feel like it is installed correctly since I have had some rides where it was solid. My first thought is to change the battery.
Any guidance would be greatly appreciated.
Thanks
