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.

Thanks Guys, I am pretty sure its the pot. I have one ordered should have been here today. I will let you know if that fixes it.
The code 2 is a normal status before travelling. The code 8 should be flickering, but should not come on when you first move the control handle out of neutral. The code 8, flickering means that the truck is trying to go into high speed. The code 5 is the status for normal travel. The code C is for when the system senses too high a voltage at the #1SCR. I would check the potentiometer in the handle first after checking the battery. Then I would check the drive motors and the heat-sink for the #1SCR and the #1SCR. You said that when you push the contactor in manually the truck takes off at high speed, that is not normal. It usually means that the #1SCR is shorted or that the "M" speed contactor is welded shut. Hope that this helps!
Stam is right (imnsho), that is the very first step.
I would also offer to make sure there is a static strap, and to pull the battery out and clean all the corrosion out from under the battery.
check battery under load.
