I’m having trouble with my bike computer speedometer after I put my racing wheels on. Worked fine with my training wheels. All I did was move the magnet from my training wheel to the old 404 front. I’ve been fiddling around with the magnet alignment with the sensor but can’t get it to give a speed readout on the computer. The sensor clicks and lights up indicating that it’s sensing the magnet but it won’t give me a reading. I didn’t move the sensor or computer at all from when it was working with the training wheels. Any idea what’s wrong? Or ideas for troubleshooting. The computer is a sigma 1609
