Genie S85 S/N 1708 year 1999 - Hydraulic problem

samedi 27 août 2016

Hi guys,
We bought 1 Genie S85 S/N 1708 4WD year 1999 and we have 1 problem with Hydraulic system.
When we operated the functions, if there was no voltage went to Valve item G Name: Valve G.jpg Views: 2 Size: 89.1 KB, all of the functions didn't operate.
If we bypass the electronic signal and provide electric to Valve G, we can operate the functions. However, the hydraulic temperature will increase rapidly and after 30mins - 1hour the machine will stop working.
We have checked 1 Genie S85 year 2000 S/N 1895 and found out the Valve G received electric only when we lower the main boom. All remaining functions, the valve received no electric.

We tried to replace the valves with similar valves but couldn't fix the problem.
We have also tested the wiring diagrams and made sure it stays the same with Genie S85 year 2000.
Did anyone face the same problem with us ??
We have been fixing this machine for half a year but didn't make and progress.
We also contacted local Genie Dealer but they didn't support used machine.
Here is the schematic of the hydraulic system ( we downloaded on Genie).Name: Valve G location.jpg Views: 2 Size: 23.5 KB
