M510 Remote does not switch on battery/display

[Puschtrale]

Hi guys, after some problems that i have had with water in the cables (resolved it with the hair dryer) my bike now has another peoblem: i cannot switch the bike on with the third button on my remote. I just tried the Besst Tool and while connected display and the remote were ok (i tried it out cause with the On/Off button on the frame in position Off the display first shows 0%, for reading the controller in the Besst Tool you then need to switch ON the On/Off button on the frame, then battery showed 100%; the display was always on while connected to the Besst Tool and all menu options worked fine with all 3 buttons on the remote). I even tried to recalibrate the position sensor with success - the motor was spinning for a few seconds like it should. I updated the controller with the new firmware - succeeded. Afterwards when disconnecting Besst Tool display was shutting off as normal. After plugging in all cables like it should, pushing them inside pretty hard so that all connections were ok i tried to switch on the display - nothing.
Does anyone know what options i have to start the display and battery without using the remote? Is there any option so that i could proff that the motor is working?
Does anyone have another idea where the problem might be ?

Check the pin from the switch button to display (asssume your display C240), i used bend one of the pin. after fix it it's normal again.

What do you mean with the pin from the switch button to display and what do you mean with "i used bend one of the pin" ? Yes, my display is the dp C240. Thanks if you can give me a better information for understanding what you suggest me to do.

If you ment that a pin might be bend i can tell you that this is not the error. All pins looks good to me

I had the +- same problem with my M500. It started one time after several week of use. When i can't reinit the motor after it is pass in "standby" mode during lunch time stop. After lot of manipulation i could restart. i have invalided the economic mode and i could use the bike during 3 months, sometime i couldn't switch off at the end of exit, but i could with the on/off switch of the battery. i have tried with several display/remote switch and always the same problem. I have suspected that it is one component in controler who fail when it is hot ? (the only electronic part that i couldn't replace). But one day it finish by i could't init to start at cold. After long fight with dengfu/bafang (mostly because i couldn't purchase an controler at this time), bafang have accept to take in charge my controler in her european service center. i have sent my controler/wire/display, they have test it and they didn't find an failure, but they have accept to perform standard exchange of the controler. since this time (more than 1 year), no problems. good luck. i have purchased one spare motor to never need to have necessity to request one more time repair from bafang or dengfu. It's the game, motor is less expensive, but when it have failure, you are alone. I purchase it in knowledge and at finally i'm satisfied, because i have ordered one M510.

How did you fix it?

I have swapped the controller, the head unit display and the main wiring loom. - Nothing.
Thanks in advance. Mark
