I bought my first ebike kit 2nd hand last year and I've been using it every day to commute to work and love it to bits. The kit consists of a 36V 9Ah battery, Crystalyte 408 motor and Crystalyte 36V 20A "Journey" controller.
Unfortunately it let me down this week, the motor started stuttering (although the power LED's on the throttle still stayed bright without flickering) and then the motor cut out completely and hasn't worked since.
I did some tests this morning, here's what I've done so far:
-tested battery voltage. 40V from the 36V nominal lithium ion, so battery isn't flat
-also have voltage at controller side of anderson connector between battery and controller so not that
-unplugged PAS sensor, brake cutout, 3 mode power level switch, battery gauge etc so I just have battery, controller, thumb throttle + motor. No change.
-have swapped throttle for replacement throttle, not that
-unplugged and cleaned motor phase connector, not that
-unplugged and cleaned motor hall sensor connector, not that
-connect battery directly to each motor phase briefly and wheel moves each time, so motor windings are ok, not that
-took apart controller case and identified the hall sensor wires. Voltage between red and black wire fluctuates constantly between 0.6 and 13 volts. Ummm I expected this to be constant, probably 5V?
Anybody know much about these controllers? Photo is of my controller, hall wires are the plug on the far left. Any idea what I can try next?
