I just changed battery in my Specialized power crank, with a Garmin Edge 520. Never had any problem with it. Now I get cadence readout but no wattage. I've tried turning unit on and off, taking battery out and replacing it. Thoughts?

I don't know if you need to perform a calibration on that power meter after replacing the batteries.
I do have the same problem. I changed the battery in my SRM and now I have only cadence readout but no wattage. I already calibrated the power meter, changed the battery and finally restore the factory profile of my Garmin Edge 520 but nothing changed.
My thought is the your power meter has failed. With about half the power meter failures I had over the last 15 years the cadence would still work, but the power was 0 or power would be erratically appearing on the display. My question is is the power you see 0 or - - -. Becauce if is 0, that means the crank is transmitting power. But because the PM is not working properly that power is 0.
