Kelly KHB Controller & Brake Sensors

Brake Sensor Error

After some under the hood work (more on this to come), I was testing some rewiring and powered up the Kelly controller.  It indicated an error condition with the blinking red LED of 3,3 "Hall throttle is open or short-circuit".    30 minutes of debug of the Throttle sensor yielded no apparent issues.  Then I remembered having turned on the Brake Sensor setting in Kelly configuration software previously.    Since the brake sensor wiring needed some extensions, I had yet to connect the sensor to the controller.

Key lesson:  The controller reports the 3,3 error for both the throttle or the brake sensor.  Once I connected the brake sensor, the error cleared.   This is a great undocumented feature.
