I bought a new Bell 8 function bike computer a few years back. I had intended to install in on my (then) 2007 Royal Enfield 500 Bullet motorcycle, which had an unreliable speedo/odo on it. I never installed it and sold the motor cycle. Then moved. So I decided to install it on my mountain bike. Opened the package and installed per the instructions. Sensor goes on LEFT fork leg, install magnet to within 1/32", etc. It turns on and I can set the wheel size, set for mph or kph, set the time etc. Go on a ride and won't read miles per hour. Came back and tried spinning the wheel both ways....nothing. Set the sensor closer to the magnet....nothing. Any way to bench test one of these things?
Thanks, Jon
