Here's another update: My 2020 Zero SR/F Premium has been in the service department at Grand Prix Motorsports in Littleton, Colorado for over 11 weeks now. I brought it there in March to fix this problem where it won't charge.
They asked me to come in last month to remove the eMoto Design double-J charging kit. Fine, I did that, on May 20th. And now, once again, no progress is being made. I'm confident the eMoto Design double-J charging kit wasn't the problem -- this problem occurred sporadically before I installed that. Regardless, neither Zero nor Grand Prix Motorsports appears to be doing anything to solve the problem.
We've had lots of great riding weather. My 2-year-old top-of-the-line Zero has been out of commission for so long now that I've canceled the insurance.
If I could get a factory service manual, I'd happily fix it myself (I have an electronics background, and a Master's in Computer Science). But Zero won't allow us to fix our own motorcycles.
Sorry to share negative experiences, but I don't feel good about keeping this quiet.
Cheers,
- Fred
