I know I have been posting so many TSDZ2 related questions but...
My 52V TSDZ2 with 860C and OSF 1.1.0 failed again today, at a 2500km mileage. I left home with a full battery at 58.8v and things started to go wrong after riding for 20 minutes, when power delivery started to pause for short (<1s) gaps. Over the next 15km trip this worsened quickly and the output became intermittent, like sharply off and on once per 1 second or so. It was not the brake/shift sensor because the monitor would indicate a "brake" sign if it was, which was not the case. Probably not the torque sensor since it would have caused the power to rise and drop in a ramp, but the assist went off and on rapidly as if the brake sensor was frequently triggered, and full throttle won't help. I also don't suspect the speed sensor because speed reading was fine. Oh yeah, I hooked up a temperature meter to the stator of the inside motor and kept its reading under 99 degC.
After resting for half an hour without turning off the monitor, I started riding home. In the first half mile it was at least still giving intermittent power. Note that in the short periods when it was giving power, the power magnitude was usual. Yeah it was really jerky with me pedaling hard in that situation. Till this point the monitor was good.
Until all of a sudden it gave way completely. No power at all. Monitor blacked out. At this moment the battery was 50.9V. If I hit power key shortly after it was dead, the monitor blinks and blacks out again. I could wait for several minutes and then would be able to start it successfully. But after working for a short while (depending on how long I had waited since its last failure) it's dead again. After sitting for hours it can power up now and idle on throttle, but I'm sure it'll fail again if I ride it.
Did anyone experience similar issues, and could someone help me troubleshooting? Any advice is appreciated.
