I just purchased a pair of XC200 pedals. My first ride calibration data seemed off and it had my average power at 353W which I know is not correct. My second ride I allowed calibration before I started and the data looked really good for about 25 minutes and then something appears to have happened with my right pedal. You can see that my L/R balance goes out of wack. What's confusing is that the data cuts out and then comes back at lower settings. My first thought is to swap in a new battery but Garmin Connect says the battery levels are fine.
From other posts, it sounds like things to try are re-seating the battery and the battery cover, confirming crank arm length setting,etc. Anything else to try?
