I must have jinxed myself with a thread last month about my problem-free installation of a Polar power meter. It has now gone flaky on me. I have lots of clues about what must be wrong, but I can't put it all together. Can anyone help me solve this mystery?
On my last outdoor ride, the cadence & power output disappeared for the last hour of the ride. But I did NOT lose the speed reading. I'm pretty sure that means all the connections must be good.
I thought perhaps the cadence magnet was out of position (and that the power reading depends on cadence). But I get green LED flashes when the crank arm passes the pickup, so the sensor is definitely registering the cadence, but the signal doesn't make it to the display on the bars.
On a trainer ride today, the cadence & power came back, but intermittently. Under effort, I'd get cadence and power readings, but when Coach Troy told me to soft pedal, I'd lose them both. I still had a speed signal the whole time.
Last clue: even when I had power, the power numbers were crazy. They registered at 700 - 1200 W, when they should have been reading 150 - 300 W. After seeing this, I tried repositioning the chain speed sensor, but that didn't seem to change the power readings. I also tried moving the big "cigar" sensor around a little, with no luck.
I'm stymied. Can anyone tell me which component is likely to have gone bonkers? And whether it's any use to try reinstalling / repositioning, or should I go straight to Polar?
