I have a new magnetless cadence sensor (on its own - no speed sensor). Unfortunately it doesn't seem to be working - the little LED doesn't flash when I spin the crank, even after a minute or so. I've reset it by taking out the battery, and it flashes red/green and then green for a few seconds like it should - but after that, nothing.
Is there something I might be missing, or is it likely that I've got a faulty unit?
Thanks,
Steve.
