    I'm trying to extend the wire lead out of my 4-year-old, Specialized, wired cyclometer so that I can use it on the back wheel of a bike that is used only for cycling on a trainer. I soldered in two wires (different gage than the cyclometer wires) to do the extension and the cyclometer won't work when I spin the wheel. The magnet is correctly position near the sensor. Could it be that the new, extension wire that I soldered in is creating too much resistance to where the computer can't read it correctly?
    Thanks

    Resistance shouldn't be an issue. I've extended computer wires by as much as eight feet without malfunctioning. First, check for shorts and continuity by measuring the resistance across the contacts on the computer mounting bracket. If that checks out and it's still not working, try switching the leads on one of your connections. I'm not sure if the polarity matters, but since most sensor wires are marked +/- it might.
