Hi,
Two weeks ago I had to replace a controller in my BBS02b motor due to water ingress inside the controller which caused error code 12.

unfortunately today I have noticed another problem, the motor just cuts off with no error on a display. When I tried to restart it several dozen of times it went on for a while and cut off again. The battery is fine and gives 52v. I have checked connectors from brake and gear sensors and they are dry. When I plugged in a throttle and pressed it several dozen of times the motor went on for as long as I was pressing the throttle. When I released it the motor went dead again. Every 30-40 attempts and it goes on untill I release it.

I did not check the controller yet but I doubt there is water in it its been sealed properly with a liquid tape.
Any Ideas?
