« on: March 13, 2025, 04:23:54 PM »- Today while trying to charge I got an "Isolation Fault" and was unable to charge (no water, just maybe some humidity on the garage). I got some errors on the dashboard and was only able to charge after 5-6 hours waiting. Then the errors dissapear and after a full charge I was able to ride again.Almost new buyers of Zero got this "Isolation Fault".
I got BMS logs with dealer.
Conclusion : it's a software bug, because faut is with higher Mohms value as fault clear.
In my case, 2000km with Zero S and 3 monthes, already "3 isolation fault".
4702238 ohms => Fault set ... 3354997 ohms => Fault clear
5008448 ohms => Fault set ... 2548091 ohms => Fault clear (this time with also "Battery Ineligible" set)
2846579 ohms => Fault set ... 2033755 ohms => Fault clear

which firmware version gave you the error?
I have a 2024 S, so far so good and I'm a bit afraid to update the firmware. At the same time, staying behind also makes me nervous, since I don't know how smoothly a multi version update will go.
Oh damn, how I wish. it was open source, so we could do our fixes ourselves
