I have a 2006 jcb 8080 excavator that has a button to change over the control mode, but now it randomly does it on its own??? Any ideas what's causing this?

Is it the 180 degree swing or the 2 speed tracking?
Or is it ISO to SAE for the hand controls?

It's the hand controls. The upper boom is switched from one stick to the other .

So that means its the ISO to SAE control then, which should look like this and i would say one of the solenoids is playing up or you got a wiring issue also check the switch is ok .
If only one circuit is playing up you could swap the coil/cartridges from left to right or disconnect the coils and see if that holds it in one pattern.

Forgot to add that this valve change over will be located at the 180 degree pivot area of the cylinder end of the ram under the cab.
Also remember if taking the solenoids out to depressurize the servo /pilot circuit ignition on engine off and wiggle all levers to vent accumulator.

So for the upper boom to be switched fRom one stick to the other that's the only difference between iso and sae? And when you say it's on the end of the ram under the cab what's the best way to achess this? There's a big round plate under the machine will I take that off and go up threw?

Looking for a part for a JCB excavator. Part # 25-221942. Solenoid coil. That's the solenoid that failed, switched it with another and fixed the problem. But I still need the coil. Know where I could order this? Dealer is crazy expensive. I'm in newfoundland Canada
