casainho said:Can you explain what you did when that did happen, step by step? Does it happen always to you?bynnek said:I just upgraded to the v.0.6.8 on my SW102 and also v55 for the motor. I'm still getting the unintended motor power when exiting the configurations page. After I the motor blips and lurches, I see the little text on the screen saying the "motor is initializing" or something. I don't think the fix for this bug is working as intended.
Thanks for reporting. I think it is unfortunate what did happen to you. I can't have throttle in my ebikes so I can't test the throttle... But I didn't changed the code related to throttle.ezrider1199 said:OK - what the hell is going on here. i flash the new firmware, setup my configs and change the temp sensor to throttle control. i exit menu and test the throttle a very little and the bike just LURCHES full power and wheel wont stop spinning. pretty much everyones ebike worst nightmare. it runs into my coffee table and spills a cup of wine onto my carpet. i had to go reach the battery shutoff, damaged my floors too.
can someone CONFIRM THAT THE THROTTLE IS WORKING!?
edit: FORTUNATELY im not insane and this is a reproducable problem. everytime you change the setting from "disabled" to "throttle" it starts behaving like this. BE CAREFUL!

What I think is important is a BIG notice saying for users to test the first time with bicycle with wheels on the air and ready to hit the brakes and disable the battery power because this kind of issues can happen due to a bug in the firmware or incorrect configurations. This should be true for first time installation as also firmware updates.

casainho said:1. Check to see if you are hitting the max PWM value, cadence, etc. Would be great if you could compare this values between the firmwares and get technical detailed information about what can be different -- compare the source code of both.
2. Don't know, that does not happen to me. Try reset to defaults and see it that solves.

As soon as I'm done, I'll post the code and description of the change.

Seems to me that the power source is failing. Maybe the BMS is cutting the power for any of the reasons it should do it.hefest said:Had an interesting situation today.
Powered bike and everything looked fine. Once i started pedalling i noticed there is no assistance at all. Display (sw102) went black. Tried powering the display again, no luck. After several attempts display came back to life and I started riding. Very quickly while riding I noticed display powered down again, but this time the motor assistance was not stopping. I tried braking (i have brake sensors) as hard as I can but the damn thing would not stop, motor was still pushing forward. When I finally stopped everything was dead. Display wont power up, led indicator on battery was not working.
I removed the battery and switched it off and than back on, led display on battery is now working. As soon as I put the battery on the bike it stops working. After power cycling battery led indicator is again on. Battery is showing correct voltage in on positions with multimeter.
I tested battery pins on the bike and there is short circuit. Stripped down battery holder connector and the one on the motor. Now when i test power leads with multimeter on the motor it's showing short circuit. Is this normal? Can someone test on their own motor if power leads are showing short circuit?
I inspected motor wires and everything looks ok, nothing damaged that could cause short circuit.

About the motor assistance not stopping, that is something I need to improve on motor and display firmware. I need first to figure out current issues and then make motor stop if there are no communications between motor and display.

I have tested my motor and get no continuity between the positive + negative terminals with the battery removed.
shodr said:One more question. I do not want to splice the display cable on VLCD 5 but want to use cable like 1t4 sold by
https://www.electrifybike.com/store/p116/1_to_4__Female_Cable_for_TSDZ2_Open_Source_Firmware_%28OSF%29__Upgrade.html#/
but he does not deliver to my country, Slovenia. Is there an alternative source.
Regards.
So I would say there is a short circuit on the motor coils or on the 3 motor phase wires. Disconnect the phase wires from the motor controller and test again. The motor will resist to turn by hand while it is in short circuit.hefest said:Another thing, motor is resisting pushing the bike back (when unpowered).
