allen screw is tight now and i played with adjusting forward and reverse switches, forklift is atleast moving forward and back now but still slow. potentiometer readings are not correct, manual states 4300 to 4600 ohms at neutral and i'm getting 1.9k... also tb11 terminal 1 is 3.5v with key off and changes to 0.5 with max handle movement... with key on terminal 1 is 30v...

im pretty sure the pot. is bad because it doesn't have the resistance it should but could it really be the entire problem?
