No green light on Cadence Sensor 2

Tried again and found the the video. My problem is my sensor doesn;t blink

I have the  same problem. I've tried everything that has been recommended in this forum but the green light has never blinked. It's frustrating.

I have a new Cadence Sensor 2 that I disassembled before trying and now can't see how to reassemble it.

1) Do you remove the white sticky paper that is on a metal piece that also comes out?

2) Where does the metal piece go - in the basis unit or in the battery cover?

3) Finally - which way does the + side of the battery go? The manual shows the + side facing up toward the battery cover.

If you can help me solve this it'll save me a trip back to the store it came from AND I'll have cadence tomorrow.

You have not to remove the white sticky paper. Look at this review at amazon.com, then you see where the problem is.

"The battery is held into the cap by a small tin cage with small tabs. The larger of these tabs is a contact point that makes the circuit complete to give power to the unit." ...  "That contact tab was not bent over into the provided slot. Once I bent it over the sensor worked fine."

It looks that Garmin assembled some Cadence Sensor wrong.

Did anyone get a resolution on this?  I've seen this question asked in several different ways on the internet and no definitive answer anywhere!!!  Can anyone give a straight forward answer to this, please?

This completely fixed my problem.  Who knew all these sensors were shipped without good battery connections.  Thanks to the Amazon customer, I know have a functioning cadence sensor.

I hope, too, that somebody has found the solution.

I think many of us don't have a battery contact problem --- the green light blinks when we close the battery cover.  However, when we spin the sensor, it doesn't wake up and blink. For my two sensors, they sometimes start after a few seconds, often after 20 - 30 seconds, sometimes not at all.  I have cleaned the contacts and bent them upwards --- so I think the battery is well connected.  When the sensor is connected, the battery status says OK.

Yea same problem as you. Got the speed sensor working just can’t seem to wake up the Cadence sensor. Not sure what to do.

I may have found the solution to my problem.  I had a nearby magnet mounted for another wired speedometer.  It didn't affect the cadence measurement, but it may have prevented the cadence sensor to wake up.  After I moved the cadence sensor further away from the magnet, it wakes up instantaneously.
