How can I tell if a gear shift sensor is working? I picked up a great BBSHD mountain bike build secondhand. It has a gearsensor dot com brand gear shift sensor installed and a Bafang 500C display. The display does have a brake cut-out indicator light--it's yellow in the lower left-hand corner--that works well whenever I brake. Should that also light up and cut power if the gear sensor is working? Or is there no gear sensor indicator light on the Bafang 500C display?
Bit of background: the one problem with the bike was that when upshifting to the smaller gears on the rear cassette, the bike wouldn't always shift immediately, almost as if the shift cable was sticking when I gave it more slack. Downshifting was no problem. So I cleaned out and gear shift sensor housing, lubed the sensor wheel, and roughed up the cable and sensor wheel and now shifting is much better. But I can't tell if the gear sensor is actually cutting power, since maybe I've never had a working one and I'm not sure what it's supposed to feel like, and there doesn't seem to be any gear sensor indicator lights on the display.
Any insights much appreciated. Also, would getting rid of the stock BBSHD front chainring help with the delayed shifts?
