I moved the cable while it was connected and got no response. I also took a pretty strong magnet and waved it all over the sensor body while it was connected and also got nothing. I bought a new one and will hook that up in place. Hopefully the cable slides more easily and it works to sense...

It's definitely broken. Got the bike up on a stand and it wasn't cutting power. There may be an indicator light on the actual sensor housing that doesn't light up either. Anyway to troubleshoot it? I'm guessing it's a problem with the sensor cable, perhaps a too-tight bend in the routing to the...
