Hi, I am having an issue with a Clark Electric Fork lift. TM 20 serial number TM2-17-0539-6628FA. Had a local forklift repair shop come and they said problem was Accelerator pod. We had it rebuilt but problem I have now is that I wired the plug back to the matching wires and have one white wire left and can't find where it goes. I have the Operators Manual and the Wiring Diagram only shows 4 wires to plug. With out the white wire hooked up I get clicking to the back both forward and reverse. Any help will be much appreciated.
