The basket is currently 20' in the air. The only controls that work up there are starting the motor, throttle and the horn.
The only function that works on ground controls (besides motor) is boom down. It is next to the side of a bin so we can't let it down with out moving it. I feel like we don't have oil flow, because if I use jumper wires to activate a solenoid, I still can't get it to move. The last thing I was doing when it quit was raising the jig. Any ideas? Thanks

Machine is level. I'm wondering about all the safeties.
Don't know about pump, is there anywhere it could be bypassing?
Thought about ground, but put jumpers from solenoid to power and ground, and nothing happened, thus eliminating the ground theory?

I agree with this, likely a axle extension switch. That is why it will only allow down function until the boom down switch is made.
That is if it is level and tilt sensor is working correct.
If it will go down only, I really doubt it is hydraulics related at all.
Genie has really good trouble shooting tips in the online manual

Also, I can't remember every machine, but instead of using the engine for power use the backup 12V pump. When you use that pump on some machines, it will bypass the safety stuff and allow you to get the boom swung and down. That works on some machines. I know some genie's do that, not positive yours does.

I worked on a Snorkel lift one time that had a master solenoid. You had to have power to that one AND the one that controlled the function you were trying to use. It was tied to all safety stuff. Might look there.

Either the relief valve is stuck open (won't build pressure with it open) or the pump coupling is shore (spelling?). I would start with the relief valve on the pump. Here is a link to the parts diagrams: http://www.genielift.com/en/service-support/manuals/

We had a similar problem this spring on our s-40. open the cover of the controls up in the basket and look for a loose wire. I hate all the safties but know they're there for a reason!

We got the boom turned and down. This was accomplished by disconnecting a switch on the back of the boom that runs up a ramp as the boom raises. As long as that switch is discconected all boom fuctions (seem) to work, but I feel we still have low pressure as the steering hardly works and the jacks won't raise the machine.
Still trying to study the 300 page tech manual (Thanks Jay) for more ideas to try.
Wheels appear to be all the way out, and switches look ok.
Have looked at most relief valves.
Just seems like we are low on pressure. Maybe bypassing somewhere, and as soon as I hook that switch back up things come to a halt.

For those of you that have ran an S 80-85. Did the jacks have any problems raising the wheels off ground to extend axles out? When this 1 was delivered ( not ours, but a friend's who is letting us use it) it didn't have enough lifting power to get wheels off ground. Wondering if thats normal, or if this one is weak. Bring me back to low pressure. Really need to get a pressure gage on it. Thanks

Yes the one we used had wasn't a powerhouse for lifting itself. Than again I'm not sure it was running that great as it didn't have good hydraulics in terms of flow. At low idle it would do all the functions just as fast as it would reved out. Only time rpm made a difference was driving in high speed.

Ours does the same thing. It has to do with the boom. It cant be too high or to one side or the other and has to be fully retracted. The basket switch has to be off. When ours did this one cylinder would go down and the other up. We were not on level ground to strart with. My dealer is in Flora IL. Not at home to get you ph#.
