I have seen your e-mail and your PM. Sorry, but I struggle to answer messages over the weekends these days... need the rest at my ageI have PM'd and emailed Yes. no reply as yet but its only been a few days so will hold out on creating the new thread lol.
just read a similar issue was resolved with a new battery but im not convinced they had the same exact issue as it sounded more like the connector issue but if a battery has a damaged cell how does one find that out ? surely that would throw an error at least !
The battery holds and chargers like it always has, new sensor fitted and the side display / controller type A definitely doesn't have its own internal battery. Ive got my battery as tight in the downtube as it can be ( almost impossible now to budge ) so no random movements for disconnection.
Whats even stranger now is..... that once the initial cut out occurs it will also repeat even if im just coasting with no motor use at all lol.
such a shame as the only thing that's been bullet proof and reliable with this Haibike was the motor.
Hey Zimmer, You wanna buy a super light heavy weight ahead of its time tank ?
I was interested to watch your video (Day 3). When your motor stopped assisting, I could hear that it was still running, but had gone into "limp" mode, this then carried on until it looks like the motor switched off altogether? If this is exactly what happens at the end of your video, then it is a PCB fault.
Not sure if you do this or not, but the PW-ST has been fitted with anti tampering software, that sends the motor into limp mode. I don't think this is the issue with your motor, if it did cut out at the end of the ride, because they don't usually do this. However, the bad news is that so many people killed their motors with de-restrictors, that these PCB are currently unavailable from Japan. The other issue is that Yamaha are changing the software on all their new motors and PCB's to do the same!
We have been waiting 6 weeks for new PCB's so far, and finding one is not looking good... You maybe looking at buying a new motor?
