Quarq SRAM s975 Stopped Functioning
About 6mos ago, picked up a used power meter. Works awesome, ride any wheels I like, etc...
I replaced the large chainring with a SRAM 55t ring for training purposes. Then, about 1mo. ago, it stopped working. Garmin 500 apparently receives no signal whatsoever. I've tried my son's Edge 500 that picks up the signal from his PowerTap, and it doesn't work either.
I'm wondering if the magnet for the s975 has fallen off my frame (appears that way as I cannot see one). Either I knocked it off accidentally or maybe during a crash. Would that prevent the power meter from sending a signal? I thought they were only for calculating cadence and not directly measuring power output. Anyone confirm?
