When the joy stick is activated to Right or Left, the lift goes up. Does anyone know what is causing this problem? Checked wiring - everything is ran correctly.
Perhaps there are some diodes missing in the wiring harness! The diagram doesn't show where they would go.
I received the lift in this condition and don't know what else to check - ANY SUGGESTIONS?
I can't find an electrical troubleshooting manual online. I can find the manual - but not for the electrical system.

I've been there - I don't see any troubleshooting at that site.
Do you know of someplace else to look?

Thanks, Robert

Did you look at the very bottom, Section 3 Trouble Shooting?

Try giving your local rental yard a call and talk to the service guy.

Also try JLG at: 1-877-JLG-LIFT

Have you tried calling JLG support?

Um... that would be the OP.
