If the Big Joe forklifts truck and hydraulic system won't operate, start by checking the fuse and replacing it if necessary. Then, inspect the battery quick-disconnect plug and check the battery voltage. If those aren't the issue, bypass the keyswitch to see if it's defective. Finally, check for any open circuits in the wiring and repair as needed.
