    BBS02 ER 12 solution

    I had this error after I hosed down my hybrid bike, but checked all the external wires and even changed the wiring harness. The motor stopped working and would sometimes start up after bouncing my bike around. It would work fine as long as i kept the power on. After I shut the power off for awhile and tried powering on again, the motor wouldn't run. I opened up the casing to access the controller and sprayed contact cleaner on each connector and found out that the wide connector with the tiny wires was the problem. So far so good. Anyone else have this error?

    I have an error 12 code I don't know what that means or what's going on I disconnected all connections and then reconnected everything but the screen is still blinking off and on and says er12 not once I had a faulty brake lever and I didn't change it for a while and then I did and that's when it went out I don't know if that could be the problem I would press down on the lever and it wouldn't run until I extended the lever all the way out then it would run and I did that for some time .

      According to my BBSHD manual error code 12 is "Current sensor failure - Check the controller". Maybe try disconnecting the brake sensors and see if that changes anything.
