Customer Question
My gradall forklift runs...

My gradall forklift runs good steering works fine. Boom goes up and down. Will not go forward or reverse

Mechanic's Assistant: What is the complete model and serial number of your machine?

534C 6000lbs. Don't have SN at this time

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

It's started with machine running fine. Machine engine would die and it would start back up. Then engine died and would not start. Changed the electric fuel shut off and machine starts fine. Just won't go forward or reverse

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

I tested the parking break and it works fine

Forklift is driven by hydrostatic pump. It has electric solenoids to work forward and reverse direction Are you getting battery voltage to the hydrostat solenoids? Look for blown fuse or wires pulled loose to the solenoids. Maybe ground wire loose where you changed the fuel solenoid?
