Clark ECG30:
Error -42

I have a Clark ECG 30 and it completely stopped on an employee in the middle of the aisle. It will lift and everything but it will not go forward or reverse. When you press on the pedal, it shows a code of -42. I had a new accelerator switch so i switched it out and it didn't help. I don't have a manual for this machine and not finding alot of information on this truck online yet.

Thank you for the help. I didn't see the exact wire you was talking about for sure but I did go through and loosen then retighten all connections i could see and the lift started moving. Hopefully that was all it was.
