850c 80H code and massive watt displayed !!!!

[travisraw]

I am so stumped. I have tried all trouble shooting steps from this forum. I am lost totally. can someone please offer a guiding light?

A few questions to start and assist others with ideas as well:

1. This bike has a BBS02B motor, correct? If so, it's just a few months old?
2. Is this what the display indicates when you turn on the bike?
3. The motor is not working (throttle or pedaling)?
4. is the motor making any noise and/or spinning?
5. Is the controller (right side of the motor case forward of the chain ring) getting warm? If so I'd guess blown controller driver MOSFET (not user serviceable in most cases).

Thanks for your response. Motor is bbs02b. today my display shows red battery outline with 53.1 v. motor does not spin not with throttle or pas. controller is not warm. I have tried running motor from charger direct. (no go) I have tried bypassing display (no go) I have unplugged and replugged everything numerous times (no go). Does this mean by process of elimination that it is the controller? Thanks for any suggestions.

The controller would be my best guess.

Thanks for your time i really appreciate it. Do you happen to know what the 80H code is?

I couldn't find the 80H code, and was hoping Luna might know.
