Hello all, I just did my first conversion. I used a BBSO2 with a 48v Hailong. I have everything connected but the motor isn't running and the display won't turn. The battery only lights up for a second when I press it and then goes dark but I'm not sure if that is normal. Any troubleshooting tips would be greatly appreciated, I'm not sure what's going on.

On my 500c display I have to hold the right button for a couple of seconds, then enter password 0,0,0,0.
not sure, recheck the wiring all connectors in the right places? u can also try using the bafang programming software, connecting a bafang programming cable to the display cable with battery on to see if the motor controller is operating correctly. generally its going to be a battery issue if u cant get things to power on
