Hello, good morning. I have a Pallet jack B827N44658J( serial #), that has error code AL 11, this lift was dropped off the back of a truck from a liftgate at full height, so there are obvious issues with that, but i have resolved all the other physical issues with the lift and now that i was finally able to power on the lift, it has an error code of AL 11, i don't have access to the service information where we are due to dealership rules with us, but i really need to know where to go with this, I have a feeling that the controller has an internal fault after being dropped from such a height, ive solved this before but had the information to follow the diagnosis process! Any help will be greatly appreciated.
