Hello Guys, I am looking electrical diagram for a Crown RC 3020-30 Model with 1A174414 Serial. The forklift dont have traction, the lift system is operating. I revised the contactors but the signal for the activation of the coils isn't available. The foot switches are operating. I detected that some wires of the traction controller are disconnect, I supposed that the operator or other people in an attempt for solve any problem, played with the wires, and now I dont know, where go to connect these. I appraise if you can get me the electrical diagram for revise and adjust the signals.Thanks
