Hello.

I have a 2009 JCB 436Z. Recently the hydraulics quit working for the loader arms, bucket and auxiliary. Joystick feels soft like there is no pilot pressure. Joystick enable switch has power and appears to be working. I have steering and drive.

I’m not too familiar with these. Wondering if anyone knows what the joystick enable switch activates? Is there a solenoid valve that turns on pilot pressure?

I have the manual. Has to be the worst manual I’ve ever looked at for heavy equipment.
