Powertap Not reading Power!

I get a display rather than a --- and it reads speed fine. Power is always 0 though. I don't think I've lost that much fitness. Send the wheel back? Any suggestions?

Sounds like a issue I had. I was doing an interval, held down select and lost power had a 0. It was in cycling mode or non power mode, I had no icon either(or did I?). I called Saris and they told me what to do, I cant remember, but make sure that's not the case first. I hope thats your problem, good luck.

Hold both buttons down and go to set-up. Go to menu 4 and make sure watts is displayed under Pro. You must have held the select menu button down for a few seconds while in cadence and put the computer in cycle computer mode.

Thanks for the suggestions guys. Turns out this is not the problem - swapping wheels solves it despite using the same CPU, so it ain't CPU settings. Any other ideas?

Maybe the hub battery contacts aren't making contact with the batteries?

It's transmitting or he wouldn't get the speed. Have you zeroed the torque? - TF

I had an identical problem a while ago and it was due to a bad torque tube. Try this: turn the CPU on, spin the wheel to get it transmitting, then manually zero the torque. If it still is not displaying power, then go into test mode, screen 6 (look in the PT manual if you don't know how to do this) and check the bottom display number, which is the torque offset value. It should be a number somewhere in the low 500's (there is an exact range of acceptable values, which I can't remember, but I think it something like 505-525). If your number is outside this range then the hub has to go back to Saris. By the way, when I did this, my number was something like 300.
