We have the same problem. We called in a tech from a hyster place, and they gave us a bid of around 2500 to replace the main controller board, handle, and the driver board in the handle. So, we decided to replace the main board, and it still has this problem. It would be good to find out what AL10 even means? Does anyone have the code definitions?
