Bafang BBS02 system dead

[pwnrider]

I bought a bike last week with the BBS02 system. I took it out of my car on Sunday, assembled it and tried to ride it. The Bafang system turned on at first and it moved forward with the throttle. I did a few more things with the bike and then tried to ride. The system then was turned off and it wouldn't turn back on. I have two batteries so I tried the second to no avail.

So far I've tried the following troubleshooting.
- Tried different batteries (after charging)
- Checked connections
- Tried a different display

Anyone have any idea of what might be wrong? I'm guessing its the controller but I have no idea of how to test it.

Not saying you aren’t aware of this, but the most common problem for new users of BBS## motors not turning on is not holding the button down long enough. Hope it’s that simple.
