Other side of Daymak controller 72V 2021made hidden problem from manufacturer. It is a problem of assembling in their original shop. One red wire damaged the board and other wires. The ride was crazy. Suddenly it started to go backwards, then it stopped, then normal direction, then backwards again. I was mad and couldn’t find a problem even I checked each wire that comes to the from the controller. Finally I did found that problem into the controller, it’s a bad surprise from manufacturer.
