Does it do this when you don't enable the aux hyraulics too?
Trying to work out if when you are turning the aux hydraulics on, that a coil is turning on, dead heading or if a stem is stuck on, making it do this all the time.

Why are you pushing the aux enable switch twice? What happens if you only push it once?

The Bucket functions work fine without the Aux switch on. By pushing the aux button once the right hand control switch should function when toggled. The engine does load up when the aux button is pushed once. But the bucket function for lowering and roll does not work.

As I understand the system should go into relief when both aux buttons are pushed. I am getting no response from the right hand toggle switch (located on the top of the right hand control lever).

Forgive me for having to ask this, but should the aux hyd button be pressed without an attachment being hooked up to the hyd. circuit?? What happens when a continuous hyd (such as, bush hog) type attachment is hooked up to the machine?? Do you have something that you could try like that?? If it still acts up, then the hyd. press. &/or return spool valve / solenoid must be the issue. If you can get 3,000 psi out of the aux hyd quick disconnect, then the "return" side of that valve would have to be the issue. Anyone disagree with that statement??
