hello Matthew, we're working on a Skyjack 3226 serial # 27000255 that had several issues ( no lift, no travel, no steer, etc.. ). we the help of the service manual have replaced some relays a valve solenoid and a small harness. we now can get the unit to lift. however, in order for travel ( fwd/rev ) to work we manually have to close the hydraulic contactor. we are testing if the steering works that way as well. so the issue is the hyd pump contactor does not activate normally as it should. we are working with electrical schematics that are not identical to what the unit has ( wire colors, numbers, etc... ). we think a wire(s) or connector is not in the right place. any ideas on why the contactor would close for lift operation but not for travel?

No analyzer used built in the ones with modules

What's the problem?...I can tell you what to fix or look at..I've worked on Skyjack lifts for over 20 years

first off what is the serial number of this unit?

secondly, out of all the skyjacks i've seen over the years i havn't seen any of the scissors with any sort of sophisticated motor control system, they have all been analog type units with the basic switches, solenoids, etc. No ECM of any sort, even the control in the platform is very basic. Unlike the direction that genie and JLG have gone with quite a few of theirs.

I'm not saying one doesn't exist but i myself have never seen one with any components requiring a diagnostic tool.

You can go to their website, paste this url (techpub.skyjack.com) into the top of the browser and then, once on that page enter the serial number of your unit into the box on the page to get it to show you the literature for your unit.
