Hello,
I too am having problems. I now have the KEB72451X after the first unit I was sent bricked but not before it fried two sets of hall sensors. I connected the controller exactly as the schematic states, initially the controller would only cause the motor to move 1/32-1/8 of a rotation but no more, I connected a multi meter to test the throttle and when I tested the signal connection(0v-5v) suddenly the motor began to run I was able to find a configuration which worked smoothly, I ran the motor (babying it) attached to a bike for less than ten(10) minutes and it suddenly stopped working and now it is back to where it started with a solid green light on the controller but it will not work. I have changed to all previously known working wiring configurations and none of them work anymore, I have repeated the testing of the throttle in hopes of finding a loose wire but the motor will only move 1/32-1/8 of a rotation again, I have changed the throttle to a known good one and this had no effect. everything has tested well, but does not work.
I was then asked by the Kelly rep to use the auto detect and I get 4-2 error and a 1-1 error, 4-2 is hall sensors or phase angle hall sensors so I tested the sensors low output is 39.4mv and high is 11.22v the input is 4.2v. 1-1 is not a listed error. I also tried changing the phase angle to no effect. This has taken out my primary bike for almost a month so any help would be greatly appreciated.
