I am having trouble with our Raymond dock stocker, it will move forward and reverse VERY slow and then cuts off. The board gives me code 2 when I turn it on, then when I attempt to move forward the code is 8, changes to 5 then cuts off giving me code C. If I manually push the big contactor the unit will take off at full speed. Also the steering sometimes gets a bit hard to turn, not sure if this problem is related, but at least I would like to get the unit moving again.
